Exchange Client Runs Slowly or Delays Opening with Proxy (164089)

This article was previously published under Q164089 SYMPTOMS
Microsoft Exchange Client runs very slowly or delays opening for long
periods of time when it is opened on a Winsock proxy client computer. On
IPX networks where the proxy is connecting to the Internet with RAS, this
behavior causes the proxy to auto-dial.
CAUSE
This problem occurs because of a known problem with the Microsoft Exchange
Client for Windows 95. This client makes a Winsock call even if TCP/IP is
not used on the client computer. This causes a DNS name lookup to be
requested by the proxy server. Usually, the delay for this name lookup is
increased because the proxy server must dial and log on to the Internet.
WORKAROUND
To prevent this problem from occurring, modify the global Mspclnt.ini file
(in the Proxy server Clients directory) as follows. (NOTE: Remember to
refresh the Winsock Proxy files on the client before testing; otherwise,
the WSP clients will refresh themselves every 6 hours.)
Add the section:
(For Microsoft Exchange Client)
[exchng32]
Disable=1
(For the Outlook client)
[outlook]
Disable=1
This will disable WSP for Microsoft Exchange Client, thus eliminating the
delay, and the use of the proxy to access the local computer running
Microsoft Exchange Server. You can also optionally add the following
section for the MAPI spooler:
[MAPISP32]
Disable=1
