SYMPTOMS
After you use Extensions for Windows for Workgroups to upgrade a Windows
version 3.1 for Workgroups postoffice to a version 3.0 Microsoft Mail for
PC Networks postoffice, it is not possible to access the Mail Administrator
program from within Mail for Windows.
Before the Windows for Workgroups postoffice was upgraded, the Mail
Administrator program could be accessed from the Mail menu within Mail for
Windows. After the upgrade, if you select the Postoffice Manager command
from the Mail menu, the following error message appears:
The ServerPath entry in your MSMAIL.INI file is missing or doesn't
contain the pathname of a valid Workgroup Postoffice.
