We recently went from Exchange 2003 to Exchange 2010 SP1.
Most of our staff are using Outlook 2003 SP3.
In Outlook 2003 e-mail messages take a long time to send and receive. They are running cached mode. I have read articles that talk about the UDP changes. The KB seems to be gone.
Do I need to apply any rollups as we have SP1? One other question how can I tell what version of exchange I'm running to verify SP1.
