I have Outlook 2003 and Outlook 2007 with Exchange Server 2010. Currently OWA works fine. Outlook clients get the error below when trying to connect:
Cannot open your default email folders. You must connect to microsoft
exchange with the current profile before you can syncronise your folders with
your offline folder file.
This does not appear to be related to the workstations as I have tested the workstations with other Exchange Servers (Server 2003 and 2007).
I have deleted the outlook profile via control panel and tried again.
I have rebooted the computer and tried again.
I have tried enabling encryption in Outlook.
It looks to me like a security issue with the Exchange Server.
Any help would be greatly appreciated as this is now holding up a new rollout.
The Exchange Server is a member of a DAG with one other server.
