XCLN: Err Msg: MAPI Was Unable to Load Emsmdb.dll (153076)


The information in this article applies to:

  • Microsoft Exchange Client 4.0
This article was previously published under Q153076

SYMPTOMS

The following error message appears:
The set of folders could not be opened. An unexpected error has occurred. MAPI was unable to load the information service Emsmdb.dll. Be sure the service is correctly installed and configured.

CAUSE

The error message references Emsmdb.dll, but the correct DLL, Emsmdb32.dll, does reside in the <Winroot>\System directory. The wrong file is being referenced because the Wsock32.dll is not the right version; Wsock32.dll therefore references Emsmdb.dll instead of Emsmdb32.dll.

RESOLUTION

To resolve this problem:
  • Replace Wsock32.dll with the Windows 95 version.
