We have an SBS 2008 with Exchange 2007.
Starting this morning, all Outlook users reported Outlook could not connect to Exchange.
Phones using ActiveSync and Outlook Web Access all work fine.
Later in the day, a few users started to see that there PCs would connect for a minute or two, then the error would pop up telling them their connection to Exchange has been lost.
We tried creating a new profile for Outlook, it connected fine and downloaded mail fine. I could send a receive with not delay. After we turned Outlook off, and turned it back on, it developed the same problem instantly, and now nothing I do allows it to connect, except creating a brand new profile again for the first login.
Any suggestions, from what I understand Outlook communicates with Exchange via RPC, but can't find any event log errors that same relevant.
Thanks for any advice
