UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM N-CSR CERTIFIED SHAREHOLDER REPORT OF REGISTERED MANAGEMENT INVESTMENT COMPANIES Investment Company Act file number: 811-05597 Morgan Stanley Municipal Income Opportunities Trust (Exact name of registrant as specified in charter) 1221 Avenue of the Americas, New York, New York 10020 (Address of principal executive offices) (Zip code) Ronald E. Robison 1221 Avenue of the Americas, New York, New York 10020 (Name and address of agent for service) Registrant's telephone number, including area code: 212-762-4000 Date of fiscal year end: May 31, 2003 Date of reporting period: May 31, 2003 Item 1. Report to Stockholders. Morgan Stanley Municipal Income Opportunities Trust LETTER TO THE SHAREHOLDERS - MAY 31, 2003 Dear Shareholder: During the 12-month period ended May 31, 2003, U.S. economic growth was positive but below potential. The pattern of the recovery remained uneven with a number of indicators fluctuating between strength and weakness. The relatively brief military conflict in Iraq and the ongoing war against terrorism cast a shadow over the economy and the financial markets. The sluggish economy and uncertain geopolitical outlook favored bonds and led to record low interest rates. Throughout the period, consumer spending was the best-performing economic sector. Mortgage refinancing and low auto loan rates helped keep Americans buying. However, early this year concern about Iraq dominated investor sentiment and consumer confidence waned. Confidence was also shaken when unemployment reached an eight-year high. To guard against further downside risks, in early November the Federal Reserve Board lowered the federal funds rate from 1.75 to 1.25 percent. This marked the first change by the central bank in almost a year. Resolution of the Iraqi conflict prompted the financial markets to focus on the economy. In an effort to stimulate growth, President Bush signed the $350 billion Jobs and Growth Tax Relief Reconciliation Act of 2003 in May. Tax reductions originally scheduled to be phased in through 2006 were accelerated. In June, the Federal Reserve again lowered the fed funds rate by 25 basis points to 1.00 percent. Municipal Market Conditions The yield on the 30-year insured municipal bond index continued to trend lower over the 12-month period ended May 31, 2003. The yield declined from a high of 5.29 percent in May 2002 to a low of 4.44 percent in May 2003. Throughout the period, the municipal yield spread between BBB rated general obligation bonds and AAA rated bonds provided an average of 80 basis points of additional yield. The ratio of municipal yields as a percentage of U.S. Treasury yields gauges the relative value of municipals. In August 2002, the ratio of 30-year insured municipal bond yields to 30-year Treasuries moved above 100 percent and remained there for much of this year. This high ratio signaled that municipals were relatively cheap in comparison to Treasuries. Long-term municipal volume increased to a record $357 billion in 2002 as state and local governments took advantage of lower interest rates to meet cash flow needs and refinance outstanding debt. In the first five months of 2003, new-issue volume was ahead 14 percent to $146 billion. Many analysts expect this pace to continue throughout the year as budgetary pressures force states and municipalities to actively borrow. California's share of national volume Morgan Stanley Municipal Income Opportunities Trust LETTER TO THE SHAREHOLDERS - MAY 31, 2003 continued was 18 percent of the total. New York, Texas, Florida and Pennsylvania, the next largest states, aggregated an additional 29 percent. Performance The net asset value (NAV) of Morgan Stanley Municipal Income Opportunities Trust (OIA) increased from $7.88 to $7.91 per share for the 12 months ended May 31, 2003. Based on this change plus the reinvestment of tax-free dividends totaling $0.55 per share, the Fund's total NAV return was 7.75 percent. OIA's price on the New York Stock Exchange (NYSE) decreased from $8.08 to $7.76 per share during the same period. Based on this change plus the reinvestment of distributions, OIA's total market return was 3.09 percent. On May 31, 2003, OIA's market price was at a 1.90 percent discount to its NAV. Past performance is no guarantee of future results. Monthly dividends for the third quarter of 2003, declared in June, were unchanged at $0.045 per share. The dividend reflects the level of the Fund's undistributed net investment income and projected earnings. The Fund's level of undistributed net investment income was $0.075 per share on May 31, 2003, versus $0.085 per share last year. Portfolio Structure The Fund's net assets of $164 million were diversified among 11 long-term sectors and 73 credits. Issues in three sectors, IDR/PCR, mortgage and hospitals, accounted for 48 percent of the net assets. The six states with the largest holdings -- New Hampshire, Florida, New York, Virginia, Massachusetts and Missouri -- represented 41 percent of net assets. The portfolio holds three non-income producing issues, which represent less than three percent of net assets. OIA's duration, a measure of sensitivity to interest rate changes, was 7.1 years. At the end of May, the portfolio's long-term holdings had an average maturity of 18 years. The accompanying charts provide current information on long-term credit ratings, maturity distribution and sector concentrations. Optional redemption provisions by year of call and respective cost (book) yields are also charted. The Fund's procedure for reinvestment of all dividends and distributions on common shares is through purchases in the open market. This method helps support the market value of the Fund's shares. In addition, we would like to remind you that the Trustees have approved a procedure whereby the Fund may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at 2 Morgan Stanley Municipal Income Opportunities Trust LETTER TO THE SHAREHOLDERS - MAY 31, 2003 continued the time of purchase. During the 12-month period ended May 31, 2003 the Fund purchased and retired 175,800 shares of common stock at a weighted average market discount of 5.83 percent. We appreciate your ongoing support of Morgan Stanley Municipal Income Opportunities Trust and look forward to continuing to serve your investment needs. Very truly yours, /s/ CHARLES A.

Organization and Accounting Policies Morgan Stanley Municipal Income Opportunities Trust (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The Fund's investment objective is to provide a high level of current income which is exempt from federal income tax. The Fund was organized as a Massachusetts business trust on June 22, 1988 and commenced operations on September 19, 1988. The following is a summary of significant accounting policies: A. Valuation of Investments -- (1) portfolio securities are valued by an outside independent pricing service approved by the Trustees. The pricing service uses both a computerized grid matrix of tax-exempt securities and evaluations by its staff, in each case based on information concerning market transactions and quotations from dealers which reflect the bid side of the market each day. The portfolio securities are thus valued by reference to a combination of transactions and quotations for the same or other securities believed to be comparable in quality, coupon, maturity, type of issue, call provisions, trading characteristics and other features deemed to be relevant; (2) futures are valued at the latest sale price on the commodities exchange on which they trade unless it is determined that such price does not reflect their market value, in which case they will be valued at their fair value as determined in good faith under procedures established by and under the supervision of the Trustees; and (3) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost. B. Accounting for Investments -- Security transactions are accounted for on the trade date (date the order to buy or sell is executed). Realized gains and losses on security transactions are determined by the identified cost method. Discounts are accreted and premiums are amortized over the life of the respective securities. Interest income is accrued daily except where collection is not expected. C. Federal Income Tax Policy -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable and nontaxable income to its shareholders. Accordingly, no federal income tax provision is required. 16 Morgan Stanley Municipal Income Opportunities Trust NOTES TO FINANCIAL STATEMENTS - MAY 31, 2003 continued D. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. E. Futures Contracts -- A futures contract is an agreement between two parties to buy and sell financial instruments or contracts based on financial indices at a set price on a future date. Upon entering into such a contract, the Fund is required to pledge to the broker cash, U.S. Government securities or other liquid portfolio securities equal to the minimum initial margin requirements of the applicable futures exchange. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments known as variation margin are recorded by the Fund as unrealized gains and losses. Upon closing of the contract, the Fund realizes a gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. F. Use of Estimates -- The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures. Actual results could differ from those estimates. 2. Investment Advisory/Administration Agreements Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment Advisors Inc. (the "Investment Advisor"), the Fund pays an advisory fee, calculated weekly and payable monthly, by applying the annual rate of 0.50% to the Fund's weekly net assets. Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the "Administrator"), an affiliate of the Investment Advisor, the Fund pays an administration fee, calculated weekly and payable monthly, by applying the annual rate of 0.30% to the Fund's weekly net assets. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended May 31, 2003 aggregated $12,867,040 and $17,408,171, respectively. Morgan Stanley Trust, an affiliate of the Investment Advisor and Administrator, is the Fund's transfer agent. At May 31, 2003, the Fund had transfer agent fees and expenses payable of approximately $8,300. 17 Morgan Stanley Municipal Income Opportunities Trust NOTES TO FINANCIAL STATEMENTS - MAY 31, 2003 continued The Fund has an unfunded noncontributory defined benefit pension plan covering all independent Trustees of the Fund who will have served as independent Trustees for at least five years at the time of retirement. Benefits under this plan are based on years of service and compensation during the last five years of service. Aggregate pension costs for the year ended May 31, 2003 included in Trustees' fees and expenses in the Statement of Operations amounted to $7,360. At May 31, 2003, the Fund had an accrued pension liability of $59,311 which is included in accrued expenses in the Statement of Assets and Liabilities. 4. Shares of Beneficial Interest Transactions in shares of beneficial interest were as follows: CAPITAL PAID IN PAR VALUE EXCESS OF SHARES OF SHARES PAR VALUE ---------- --------- ------------ Balance, May 31, 2001....................................... 20,932,272 $209,322 $198,360,115 Reclassification due to permanent book/tax differences...... -- -- (144) ---------- -------- ------------ Balance, May 31, 2002....................................... 20,932,272 209,322 198,359,971 Treasury shares purchased and retired (weighted average discount 5.83%)*..........................................

Federal Income Tax Status The amount of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations which may differ from generally accepted accounting principles. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification. Dividends and distributions which exceed net investment income and net realized capital gains for tax purposes, are reported as distributions of paid-in-capital. 18 Morgan Stanley Municipal Income Opportunities Trust NOTES TO FINANCIAL STATEMENTS - MAY 31, 2003 continued The tax character of distributions paid was as follows: FOR THE YEAR FOR THE YEAR ENDED ENDED MAY 31, 2003 MAY 31, 2002 ------------- ------------- Tax-exempt income.................................. $11,477,477 $11,931,193 As of May 31, 2003, the tax-basis components of accumulated losses were as follows: Undistributed tax-exempt income............................. $ 1,630,213 Undistributed ordinary income............................... 867 ------------ Net accumulated earnings.................................... 1,631,080 Capital loss carryforward*.................................. (12,523,360) Temporary differences....................................... (141,571) Net unrealized depreciation................................. (11,894,961) ------------ Total accumulated losses.................................... ($22,928,812) ============ * As of May 31, 2003, the Fund had a net capital loss carryforward of $12,523,360 of which $5,243,406 will expire on May 31, 2004, $700,037 will expire on May 31, 2006, $87,017 will expire on May 31, 2008, $4,628,820 will expire on May 31, 2009 and $1,864,080 will expire on May 31, 2011 to offset future capital gains to the extent provided by regulations. As of May 31, 2003, the Fund had temporary book/tax differences attributable to book amortization of discount on debt securities and a non-deductible expense and permanent book/tax differences primarily attributable to an expired capital loss carryforward. To reflect reclassifications arising from the permanent differences, paid-in-capital was charged $10,136,557, accumulated undistributed net investment income was credited $158 and accumulated net realized loss was credited $10,136,399. 6. Dividends The Fund declared the following dividends from net investment income: DECLARATION AMOUNT RECORD PAYABLE DATE PER SHARE DATE DATE -------------- --------- ------------------ ------------------ March 25, 2003 $0.045 June 6, 2003 June 20, 2003 June 30, 2003 $0.045 July 11, 2003 July 25, 2003 June 30, 2003 $0.045 August 8, 2003 August 22, 2003 June 30, 2003 $0.045 September 5, 2003 September 19, 2003 19 Morgan Stanley Municipal Income Opportunities Trust NOTES TO FINANCIAL STATEMENTS - MAY 31, 2003 continued 7. Expense Offset The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Fund. 8. Risks Relating to Certain Financial Instruments The Fund may invest a portion of its assets in residual interest bonds, which are inverse floating rate municipal obligations. The prices of these securities are subject to greater market fluctuations during periods of changing prevailing interest rates than are comparable fixed rate obligations. At May 31, 2003, the Fund did not hold positions in residual interest bonds. To hedge against adverse interest rate changes, the Fund may invest in financial futures contracts or municipal bond index futures contracts ("futures contracts"). These futures contracts involve elements of market risk in excess of the amount reflected in the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the value of the underlying securities. At May 31, 2003, the Fund had no outstanding futures contracts. 20 Morgan Stanley Municipal Income Opportunities Trust FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: FOR THE YEAR ENDED MAY 31 ---------------------------------------------------- 2003 2002 2001 2000 1999 -------- -------- -------- -------- -------- Selected Per Share Data: Net asset value, beginning of the period................... $7.88 $8.03 $7.79 $8.69 $ 8.80 ----- ----- ----- ----- ------ Income (loss) from investment operations: Net investment income*................................. 0.54 0.55 0.55 0.57 0.61 Net realized and unrealized gain (loss)................ 0.04 (0.13) 0.28 (0.85) (0.13) ----- ----- ----- ----- ------ Total income (loss) from investment operations............. 0.58 0.42 0.83 (0.28) 0.48 ----- ----- ----- ----- ------ Less dividends from net investment income..................

MORGAN STANLEY MUNICIPAL INCOME OPPORTUNITIES TRUST Annual Report May 31, 2003 38538RPT-11551G03-AP-7/03 ITEM 7 Disclosure of Proxy Voting Policies and Procedures for Closed-end Management Investment Companies. The Fund's and its Investment Advisor's Proxy Voting Policies and Procedures are as follows: MORGAN STANLEY INVESTMENT MANAGEMENT PROXY VOTING POLICY AND PROCEDURES I. POLICY STATEMENT Introduction - Morgan Stanley Investment Management's ("MSIM") policies and procedures for voting proxies with respect to securities held in the accounts of clients applies to those MSIM entities that provide discretionary Investment Management services and for which a MSIM entity has the authority to vote their proxies. The policies and procedures and general guidelines in this section will be reviewed and, as necessary, updated periodically to address new or revised proxy voting issues. The MSIM entities covered by these policies and procedures currently include the following: Morgan Stanley Investment Advisors Inc., Morgan Stanley Alternative Investment Partners, L.P., Morgan Stanley AIP GP LP, Morgan Stanley Investment Management Inc., Morgan Stanley Investment Group Inc., Morgan Stanley Investment Management Limited, Morgan Stanley Investment Management Company, Morgan Stanley Asset & Investment Trust Management Co., Limited, Morgan Stanley Investment Management Private Limited, Morgan Stanley Investments LP, Morgan Stanley Hedge Fund Partners GP LP, Morgan Stanley Hedge Fund Partners LP, Van Kampen Investment Advisory Corp., Van Kampen Asset Management Inc., and Van Kampen Advisors Inc. (each a "MSIM Affiliate" and collectively referred to as the "MSIM Affiliates"). Each MSIM Affiliate will vote proxies as part of its authority to manage, acquire and dispose of account assets. With respect to the MSIM registered management investment companies (Van Kampen, Institutional and Advisor Funds)(collectively referred to as the "MSIM Funds"), each MSIM Fund will vote proxies pursuant to authority granted under its applicable investment advisory agreement or, in the absence of such authority, as authorized by its Board of Directors or Trustees. A MSIM Affiliate will not vote proxies if the "named fiduciary" for an ERISA account has reserved the authority for itself, or in the case of an account not governed by ERISA, the Investment Management Agreement does not authorize the MSIM Affiliate to vote proxies. MSIM Affiliates will, in a prudent and diligent manner, vote proxies in the best interests of clients, including beneficiaries of and participants in a client's benefit plan(s) for which we manage assets, consistent with the objective of maximizing long-term investment returns ("Client Proxy Standard"). In certain situations, a client or its fiduciary may provide a MSIM Affiliate with a statement of proxy voting policy. In these situations, the MSIM Affiliate will comply with the client's policy unless to do so would be inconsistent with applicable laws or regulations or the MSIM Affiliate's fiduciary responsibility. 2 Proxy Research Services - To assist the MSIM Affiliates in their responsibility for voting proxies and the overall global proxy voting process, Institutional Shareholder Services ("ISS") and the Investor Responsibility Research Center ("IRRC") have been retained as experts in the proxy voting and corporate governance area. ISS and IRRC are independent advisers that specialize in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services provided to MSIM Affiliates include in-depth research, global issuer analysis, and voting recommendations. In addition to research, ISS provides vote execution, reporting, and recordkeeping. MSIM's Proxy Review Committee (see Section IV.A. below) will carefully monitor and supervise the services provided by the proxy research services. Voting Proxies for certain Non-US Companies - While the proxy voting process is well established in the United States and other developed markets with a number of tools and services available to assist an investment manager, voting proxies of non-US companies located in certain jurisdictions, particularly emerging markets, may involve a number of problems that may restrict or prevent a MSIM Affiliate's ability to vote such proxies. These problems include, but are not limited to: (i) proxy statements and ballots being written in a language other than English; (ii) untimely and/or inadequate notice of shareholder meetings; (iii) restrictions on the ability of holders outside the issuer's jurisdiction of organization to exercise votes; (iv) requirements to vote proxies in person, (v) the imposition of restrictions on the sale of the securities for a period of time in proximity to the shareholder meeting; and (vi) requirements to provide local agents with power of attorney to facilitate the MSIM Affiliate's voting instructions. As a result, clients' non-U.S. proxies will be voted on a best efforts basis only, consistent with the Client Proxy Standard. ISS has been retained to provide assistance to the MSIM Affiliates in connection with voting their clients' non-US proxies. II. GENERAL PROXY VOTING GUIDELINES To ensure consistency in voting proxies on behalf of its clients, MSIM Affiliates will follow (subject to any exception set forth herein) these Proxy Voting Policies and Procedures, including the guidelines set forth below. These guidelines address a broad range of issues, including board size and composition, executive compensation, anti-takeover proposals, capital structure proposals and social responsibility issues and are meant to be general voting parameters on issues that arise most frequently. The MSIM Affiliates, however, may vote in a manner that is contrary to the following general guidelines, pursuant to the procedures set forth in Section IV. below, provided the vote is consistent with the Client Proxy Standard.

IV. ADMINISTRATION OF PROXY POLICIES AND PROCEDURES A. PROXY REVIEW COMMITTEE 1. The MSIM Proxy Review Committee ("Committee") is responsible for creating and implementing MSIM's Proxy Voting Policy and Procedures and, in this regard, has expressly adopted them. Following are some of the functions and responsibilities of the Committee. 8 (a) The Committee, which will consist of members designated by MSIM's Chief Investment Officer, is responsible for establishing MSIM's proxy voting policies and guidelines and determining how MSIM will vote proxies on an ongoing basis. (b) The Committee will periodically review and have the authority to amend as necessary MSIM's proxy voting policies and guidelines (as expressed in these Proxy Voting Policy and Procedures) and establish and direct voting positions consistent with the Client Proxy Standard. (c) The Committee will meet at least monthly to (among other matters): (1) address any outstanding issues relating to MSIM's Proxy Voting Policy and Procedures; and (2) generally review proposals at upcoming shareholder meetings of MSIM portfolio companies in accordance with this Policy and Procedures including, as appropriate, the voting results of prior shareholder meetings of the same issuer where a similar proposal was presented to shareholders. The Committee, or its designee, will timely communicate to ISS MSIM's Proxy Voting Policy and Procedures (and any amendments to them and/or any additional guidelines or procedures it may adopt). (d) The Committee will meet on an ad hoc basis to (among other matters): (1) authorize "split voting" (i.e., allowing certain shares of the same issuer that are the subject of the same proxy solicitation and held by one or more MSIM portfolios to be voted differently than other shares) and/or "override voting" (i.e., voting all MSIM portfolio shares in a manner contrary to the Procedures); (2) review and approve upcoming votes, as appropriate, for matters for which specific direction has been provided in Sections I, II, and III above; and (3) determine how to vote matters for which specific direction has not been provided in Sections I, II and III above. Split votes will generally not be approved within a single Global Investor Group team. The Committee may take into account ISS recommendations and the research provided by IRRC as well as any other relevant information they may request or receive. (e) In addition to the procedures discussed above, if the Committee determines that an issue raises a potential material conflict of interest, or gives rise to the appearance of a potential material conflict of interest, the Committee will designate a special committee to review, and recommend a course of action with respect to, the conflict(s) in question ("Special Committee"). The Special Committee may request the assistance of the Law and Compliance Departments and will have sole discretion to cast a 9 vote. In addition to the research provided by ISS and IRRC, the Special Committee may request analysis from MSIM Affiliate investment professionals and outside sources to the extent it deems appropriate. (f) The Committee and the Special Committee, or their designee(s), will document in writing all of their decisions and actions, which documentation will be maintained by the Committee and the Special Committee, or their designee(s) for a period of at least 6 years. To the extent these decisions relate to a security held by a MSIM U.S. registered investment company, the Committee and Special Committee, or their designee(s), will report their decisions to each applicable Board of Trustees/Directors of those investment companies at each Board's next regularly Scheduled Board meeting. The report will contain information concerning decisions made by the Committee and Special Committee during the most recently ended calendar quarter immediately preceding the Board meeting. (g) The Committee and Special Committee, or their designee(s), will timely communicate to applicable PMs, the Compliance Departments and, as necessary to ISS, decisions of the Committee and Special Committee so that, among other things, ISS will vote proxies consistent with their decisions. 10 Item 9 - Controls and Procedures The Fund's principal executive officer and principal financial officer have concluded that the Fund's disclosure controls and procedures are sufficient to ensure that information required to be disclosed by the Fund in this Form N-CSR was recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, based upon such officers' evaluation of these controls and procedures as of a date within 90 days of the filing date of the report.
