With it being Windows 7 Home, the user gets a pop up asking for his domain credentials when he opens Outlook. This works fine and he can send and receive email without any problems. The Out of Office Assistant keeps saying that the server is unavailable. It works for him on the Terminal Server just fine running the same version of Outlook.
1. Installed the latest patches on the client
2. Run Outlook with the /cleanfreebusy switch
3. On the Exchange server, deleted and recreated the Exchange Web Services site.
Any ideas would be appreciated.
