I have some users that are complaining that when they come in the morning and start their Outlook 2007/2010, they always get the message "Updating Inbox". This in itself is not a worry but what bothers me is that the size shown is around 20MB+. If I look through the emails that they had received between them closing Outlook and starting it up again, there is nothing more than 1MB.
Is there a way I can find out what is being pulled down when the updating happens? I need to find this since this could become an issue for our remote offices.
Our network has
Exchange 2010 with 2 CAS servers and 2 MBX Servers
All users are running either Outlook 2007 or Outlook 2010 in cache mode. The issue is seen in both versions of Outlook.
