LETTER TO THE SHAREHOLDERS May 31, 1999 New York, New York 10048
DEAR SHAREHOLDER:
We are pleased to present the annual report on the operations of Morgan Stanley
Dean Witter Municipal Income Opportunities Trust (OIA) for the fiscal year ended
May 31, 1999.
The financial markets have begun to recover from last year's global economic
difficulties. The turmoil which included the Asian crisis, the Russian debt
default and the near collapse of a major U.S. hedge fund has given way to more
normal financial conditions. The major catalyst for this return to stability was
the liquidity provided by the Federal Reserve Board's 75-basis-point reduction
in the federal-funds rate during the fourth quarter of 1998.
These international economic problems precipitated a "flight to quality" rally
in fixed-income securities and U.S. Treasury yields reached 30-year lows in
October 1998. As the world markets recovered, foreign investors repatriated
funds and Treasury yields began to rise. Interest rates also rose in response to
the surprisingly robust domestic economic growth reported over the second half
of 1998. The bond market became concerned that the central bank might become
more restrictive by taking back some of the liquidity provided during the
crisis. On June 30, 1999, The Federal Reserve Board raised the Federal-Fund rate
25 basis points to 5.00 percent.
MUNICIPAL MARKET CONDITIONS
During 1998 municipal yields were less volatile than Treasury yields. This
pattern of stability continued into 1999. Long-term insured municipal index
yields stood at 5.30 percent at the end of May, only 30 basis points higher than
November 1998. In contrast, Treasury bond yields rose 80 basis points from 5.05
to 5.85 percent. During the past six months, the yield pickup for extending
tax-exempt maturities from one to 30 years averaged 225 basis points.
The modest rally of municipals during 1998 created a more favorable relationship
relative to Treasuries. Municipals underperformed

LETTER TO THE SHAREHOLDERS May 31, 1999, continued
Treasuries, and the ratio of municipal yields to Treasury yields climbed to 99
percent by December. The higher the ratio, the more attractive municipals are
relative to Treasuries. Municipals have outperformed Treasuries this year and
the ratio declined to 91 percent by May. The high-to-low annual range of
municipal/Treasury yields for the past five years has averaged from 93 to 84
percent.
In addition to lagging 1998's Treasury rally, municipals also experienced a glut
of new-issue supply. Underwriting volume of $284 billion was up 28 percent from
the prior year and approached 1993's record. Issuers actively refinanced at
lower interest rates and refundings were 29 percent of total volume. This year's
rise in interest rates has reduced the amount of refunding activity. Refunding
volume was down 45 percent in the first five months of 1999. Total underwriting
declined 24 percent.

OIA's total market return was 15.65 percent. As of May 31, 1999, share price was
a 8.73 percent premium to its NAV.
Monthly dividends for the second quarter of 1999 remained at $0.05 per share.
The Fund's level of undistributed net investment income was $0.182 per share on
May 31, 1999, versus $0.175 per share on November 30, 1998.
PORTFOLIO STRUCTURE
The Fund's investments were diversified among 15 long-term sectors and 64
credits. Non-rated securities comprise more than half of OIA's assets. All
issues are currently accruing interest. However, 3 credits totaling 6.9 percent
of net assets were accruing income but may experience difficulty with future
debt service payments.
At the end of May, the portfolio's average maturity was 19 years. Average
duration, a measure of sensitivity to interest rate changes, was 8.3 years. The
accompanying charts provide information on the Fund's call structure, largest
sectors and distribution by credit quality.
LOOKING AHEAD
The combination of a "flight to quality" and the flood of new municipal issues
made the municipal-to-Treasury yield relationship more favorable late last year
than it had been in the previous 10 years. Although municipals have outperformed
Treasuries thus far in 1999, we believe that municipals still offer investors
considerable value versus their historical relationship with Treasuries.
The Fund 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 Trust'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 the time of purchase.
On May 1, 1999, Mitchell M. Merin was named President of the Morgan Stanley Dean
Witter Funds. Mr. Merin is also the President and Chief Operating Officer of
Asset Management for Morgan Stanley Dean Witter & Co. and President, Chief
Executive Officer and Director of Morgan Stanley Dean Witter Advisors Inc., the
Fund's Investment Advisor. He also serves as Chairman, Chief Executive Officer
and Director of Morgan Stanley Dean Witter Distributors Inc. and Morgan Stanley
Dean Witter Trust FSB.

NOTES TO FINANCIAL STATEMENTS May 31, 1999
1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Dean Witter Municipal Income Opportunities Trust (the "Fund"),
formerly Municipal Income Opportunities Trust, 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 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.
The following is a summary of significant accounting policies:
A. VALUATION OF INVESTMENTS -- Portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service has
informed the Fund that in valuing the portfolio securities, it uses both a
computerized 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. 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 STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and nontaxable income to its
shareholders. Accordingly, no federal income tax provision is required.

<PAGE> 17
MORGAN STANLEY DEAN WITTER MUNICIPAL INCOME OPPORTUNITIES TRUST
NOTES TO FINANCIAL STATEMENTS May 31, 1999, continued
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the ex-dividend date. 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 financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
2. INVESTMENT ADVISORY AGREEMENT
Pursuant to an Investment Advisory Agreement with Morgan Stanley Dean Witter
Advisors (the "Investment Advisor"), an affiliate of Morgan Stanley Dean Witter
Services Company Inc. (the "Administrator"), 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.
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Advisor pays the salaries of all personnel,
including officers of the Fund, who are employees of the Investment Advisor.
3. ADMINISTRATION AGREEMENT
Pursuant to an Administration Agreement with the Administrator, 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.
Under the terms of the Administration Agreement, the Administrator maintains
certain of the Fund's books and records and furnishes, at its own expense,
office space, facilities, equipment, clerical, bookkeeping and certain legal
services and pays the salaries of all personnel, including officers of the Fund
who are employees of the Administrator. The Administrator also bears the cost of
telephone services, heat, light, power and other utilities provided to the Fund.

4. 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, 1999 aggregated $29,356,440
and $30,729,108, respectively.
Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Advisor and
Administrator, is the Fund's transfer agent. At May 31, 1999 the Fund had
transfer agent fees and expenses payable of approximately $4,000.
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, 1999 included in
Trustees' fees and expenses in the Statement of Operations amounted to $6,413.
At May 31, 1999, the Fund had an accrued pension liability of $51,980 which is
included in accrued expenses in the Statement of Assets and Liabilities.

REPORT OF INDEPENDENT ACCOUNTANTS
TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER MUNICIPAL INCOME OPPORTUNITIES TRUST
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter
Municipal Income Opportunities Trust (the "Fund"), formerly Municipal Income
Opportunities Trust, at May 31, 1999, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities owned at
May 31, 1999 by correspondence with the custodian, provide a reasonable basis
for the opinion expressed above.
