RE: UDP port probe after moving mailboxes to new 5.5 Server.
Sounds like new mail notification. Ask them to trust the new mail server. The port number is selected by outlook each time is is started. Outlook picks the next free port on the local machine. If the user wants a specific port, tell them it is specifically 1024-65535. They will also likely complain that new mail arrives slowly. P.S. Zonealarm will do the same thing. -Original Message- From: Pfefferkorn, Pete (PFEFFEPE) [mailto:[EMAIL PROTECTED]] Sent: Friday, September 20, 2002 1:11 PM To: Exchange Discussions Subject: RE: UDP port probe after moving mailboxes to new 5.5 Server.
