Exchange 2007, Outlook 2010 Error when setting Out Of Office (Automatic Replies) from Outlook: Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.
Setting this through OWA works fine.
Autodiscover is working, and all addresses are resolvable through DNS. Outlook profile created from scratch. Anonymous access disabled for EWS/OWA (IIS on Exchange box).
I'm out of steam for troubleshooting. Any ideas?
