XCLN: Err Msg: You Need More Memory or System Resources

 Last reviewed: February 11, 1998
Article ID: Q168929
The information in this article applies to:
  • Microsoft Exchange Windows 3.x client, versions 4.0 and 5.0

SYMPTOMS

When you click the Mail icon in Control Panel you may receive the following error message: 

   You need more memory or system resources. Close some windows and try
   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The Mapi.dll file, located in the Windows\System subdirectory by default, is either missing, corrupted, or has been replaced by another version.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

  1. Reinstall Microsoft Exchange Client.

  2. Expand Mapi.dll from the Exchange Client cabinet (cab) files.

  3. 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. 

       Mapi.dll File Size       Version
                 ====        ======
               1,000,288    5.0
                989,280     4.0 SP4
