16-bit Windows Mail Client Slow on Windows NT 4.0 (177941)
The information in this article applies to:
- Microsoft Mail for Windows 3.2
- Microsoft Mail for Windows 3.5
This article was previously published under Q177941 SYMPTOMS
The 16-bit Windows mail client will intermittently perform slowly on
Windows NT 4.0. This slow performance will affect all other 16-bit Windows
applications running in the WOW. After mail is unloaded, performance will
return to normal. This behavior does not exist when running the 16-bit
Windows mail client on Windows NT 3.51.
CAUSE
This problem happens because the compression routine used by the 16-bit
Windows Mail client performs slowly on Windows NT 4.0.
WORKAROUND
To work around this problem, use the Windows Messaging client that is
bundled with Windows NT 4.0 as the primary Mail Server client on Windows NT
4.0 computers. Or, disable background compression of the MMF with the
following entry in the Msmail.ini:
[Microsoft Mail]
No_Compress=1
STATUS
Microsoft has confirmed this to be a problem in Microsoft Mail for Windows
versions 3.2 and 3.5. We are researching this problem and will post new
information here in the Microsoft Knowledge Base as it becomes available.
