Problems when Outlook and Exchange components (2003 and earlier) are installed on the same computer

Support for Office 2003 has ended

Microsoft ended support for Office 2003 on April 8, 2014. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

When you install any Exchange Server 2003 (or earlier) components on the same computer as Microsoft Outlook, various problems can occur with Outlook or with other applications that use MAPI. This includes, but is not limited to the following symptoms:
  • No results are returned by a search in Outlook.
  • Error indicating there is no default e-mail client installed.
  • Crashes in Outlook.
  • Settings on the Voice Mail tab are disabled.
  • Third-party MAPI applications do not work.

Therefore, this configuration is not supported nor recommended. 
If you have Outlook installed on the same computer as Microsoft Exchange Server, you will want to use Outlook on a different computer.

If you have a workstation that is primarily used for Outlook but that also has Exchange management tools installed (for example, Exchange System Manager), you should perform the following steps to remove the Exchange management tools (assuming you want to keep Outlook installed on the computer):
  1. Uninstall the Exchange management components using Control Panel.
  2. Run the FixMapi.exe tool.
    • Windows 7 and Windows Vista
      1. Click Start.
      2. Type fixmapi in the Search programs and files box.
      3. In the results, click Fixmapi.exe.

        Note, there is no user-interface for the Fixmapi tool and there is no message indicating a result.
      4. Restart your computer.
    • Windows XP
      1. On the Start menu click Run.
      2. In the Open box, type the following command and then click OK.


        Note, there is no user-interface for the Fixmapi tool and there is no message indicating a result
      3. Restart your computer.
