We run an Active/Passive cluster of Exchange Enterprise 2003 SP2 and Outlook 2003 on the client side.
Recently we have been getting pop-up message saying "Outlook is trying to retrievedatarom the MicrosoftExchangeserver "serverclustername.domain.local"
Sometimes the pop-up correlates with an increase of the SMTP traffic which peaks sometimes from 800Mbps to 1000Mbps.
I have ran Exchange Best Practice Analyzer and I have found the following Critial Errors on both of the Exchange Server nodes:
1.) SystemPages set too high
2.) HeapDeCommitFreeBlock Threshold not set
3.) Physical Memory Configuration
The server has 8GB of RAM the 3GB switch is in place.
Does the traffic for SMTP looks out of proportion or any of the critial issues are causing this problem? Are there any other ways within Exchange or somewhere else that could help me to troubleshoot this problem?
The types of data that Outlook retrieves during this period include information in the user's mailbox, information in the user's public folders, free/busy information, and directory look-ups (check-name).
This delay can be caused by many things. Some of them are:
Exchange server performance problems client (or add-in) problems network related issues large number of items in mailboxes Active Directory related issues (performance issues etc)
