CAS-HT on one server and MBX on seperate server. Created a MBX on Exchange 2010 SP2 and now trying to connect to that MBX using OL2010 and I get the following error on the CAS-HT Server.
First check AD Sites and Services and make sure that the subnets you use are there and are assigned to a site. Next check if your CAS server is configured to handle that site: Get-ClientAccessServer | fl Name,AutoDiscoverSiteScope
