SYMPTOMS

again.

CAUSE

The Mapi.dll file, located in the Windows\System subdirectory by default, is either missing, corrupted, or has been replaced by another version.

RESOLUTION

Reinstall Microsoft Exchange Client.
Expand Mapi.dll from the Exchange Client cabinet (cab) files.
Copy Mapi.dll from another Windows computer that is currently working. Both computers must be running the same version and service pack of Exchange Client. See table below and compare the size of the Mapi.dll file to find out this information.
