  • Microsoft Exchange Client 4.0
  • Microsoft Exchange Client 5.0
  • Microsoft Exchange Windows NT client 4.0
  • Microsoft Exchange Windows NT client 5.0
This article was previously published under Q146398

SYMPTOMS

When you try to import a Personal Address Book (PAB) into the exchange client, if the PAB has an extension that is .MMF instead of .PAB you will receive the following error:
File "FILENAME.MMF" is not a recognized MMF File.
If the Personal Address Book file has any entry other than MMF, the file will import correctly. On the other hand, if you have a actual MMF file that has the extension of .PAB, it will also import correctly.

RESOLUTION

Rename the Personal Address Book extension to anything other than .MMF and the import will work correctly.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange version 4.0 Windows, Windows NT, and Windows 95 clients. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
