We have an Exchange 2010 - Exchange 2003 co-existence domain. The Exchange 2003 servers will be decommissioned soon. We use Symantec Enterprise Vault for Archiving our emails.
Users are connected to Exchange 2010 using Outlook 2007, 2010 in cache mode
Lately I have noticed that when users return to the office after having their computers shut down for a few hours, and start they computer and open Outlook, Outlook reports that it is updating the folders and seems to download around at least 10MB (this is shown in the Outlook Status bar at the bottom). However, most of the times the users do not have any new emails that have come in or have sent any emails via WebApps.
Is there a way I can find out what all is being "updated" by Outlook? I enabled Advanced Diagnostic Logging in Outlook but I do not get much info from it.
I would really appreciate help in this.
