This one is kicking my posterier so any help would be very appreciated.
Exchange 2010 with SP1 running as a guest on a Hyper-V 2008 R2 Server
Outlook 2007 Clients.
Every day my Outlook 2007 clients randomly disconnect from Exchange and display "disconnected" or "Offline" and Outlook begins prompting for username and password. This continues until the Exchange server is rebooted.
Logs on the exchange server and all domain controllers are completely clean. Clients can ping the exchange server by name and OWA works fine when Outlook has disconnected.
I've tried running the clients in and out of Cached Mode and I've tried setting the clients to "connect to exchange using HTTP" and turning that off as well, with no effect on the problem.
Has anybody seen this issue before or have any suggestions?
