Clicking Tools Menu Hangs Microsoft Exchange (152790)


The information in this article applies to:

  • Microsoft Windows 95
  • Microsoft Windows 98
This article was previously published under Q152790

SYMPTOMS

When you are using Microsoft Exchange and you click the Tools menu, one or more of the following symptoms may occur:
  • Nothing may happen
  • The Deliver Now command may be unavailable
  • The Tools menu may take a long time to respond
  • Windows 95/98 may stop responding (hang).

CAUSE

This behavior can occur if there is a mismatch between Microsoft Exchange and the Mapi.dll and Mapi32.dll files.

RESOLUTION

To resolve this issue, use the appropriate method:

Windows 95

  1. Click Start, point to Find, and then click Files Or Folders.
  2. In the Named box, type mapi*.dll.
  3. In the Look In box, click the drive containing the Windows\System folder.
  4. Click Find Now.
  5. Rename any files that meet the following criteria:

    The file name is Mapi.dll or Mapi32.dll.
    The file date is not 7/11/95.
  6. Click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs..
  7. On the Windows Setup tab, click the the Microsoft Exchange check box to clear it.
  8. Click OK. When you are prompted to restart the computer, do so.
  9. After the computer restarts, reinstall Microsoft Exchange by repeating steps 6-8. Click the Microsoft Exchange check box to select it in step 7.
  10. After you reinstall Microsoft Exchange, reinstall the Microsoft Exchange Update. Make sure to install the update from an empty folder on the hard disk.

MORE INFORMATION

One cause for this behavior is running the Microsoft Exchange Update (Exupdusa.exe) in either the Windows or Windows\Desktop folder. Doing so causes a newer version of the Mapi.dll and Mapi32.dll files to be extracted, creating the version conflict.
