Selective Slow Email - Exchange 2003

dmboshers asked
Last Modified: 2008-01-09
Some users on our Exchange 2003 (Enterprise) system are reportin gslow response for email. In other words an email will be sent to them - internally or externally - and it will take 20 to 30 minutes to arrive. The sytem and applicationlogs don't seem to indicate any relevant problems. What else could cause this?  Ity''s not happening for everyone and its not happening all the time. Any help would be greatly appreciated. Thanks.

Some areas that may be of trouble:-
Outlook 2003/2007 cached mode - try turning it off.
Windows Firewall (or other firewall) - temp turn off, or add exception to allow Outlook to communicate to the Exchange server subnet.

Best of luck!


Thanks but this doesn't seeem to be the problem in our case. Any other ideas?

Do you have just one Exchange server, or multiple - and how many have message stores?
Internal e-mail being slow sounds very strange - if you could log into OWA on the users that aren't getting e-mails quickly & see if they show in OWA quickly. This would rule out your Exchange server and lead you to concentrate on the Outlook client/server communications.


Good idea. We have only one EXchange server in this location and about 70 users. We have 4 infomration store. Yes, its very strange that its happening to some people bu tnot others.

Let us know how the OWA monitoring goes.  Also another tool to use: enable Message Tracking on the Exchange server - then look at the problem e-mails (especially delayed internal ones) in message tracing center.


The problem ended up being that we were being hit with thousands of phony emails from around the world. Our server bounced all of them but the drag on tthe system was such that it couldn't keep up. We solved the problem by usin gnon-account bouncing in Postini so now they are fielding the phony emails and we are functioning fine. .
