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.
