Every time an outlook client connects to my internal mailbox/cas or external cas/outlook proxy I'm getting event:
Log Name: Application
Source: MSExchange Autodiscover
Date: 2011-03-25 13:56:42
Event ID: 1
Task Category: Web
Unhandled Exception "User setting 'PreferredSite' is not available. "
Stack trace is empty so no details on event.
Everything works fine - autodiscover, outlook anywhere and internal clients can connect to Exchange.
I suppose those events start to appear after adding another DC on remote site.
Should I worry about server condition? How to get rid of those events?
