Greetings.

I've just set up a brand new Exchange 2010 SP2 server. Everything has been working great. OWA, mobile phones, and anyone using Outlook for Mac 2011.

Windows users are unable to connect to my server though and are given this error:

"This action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."

The server is set up as a multi tenant environment however NOT using the /Hosting switch. SP2 allows you to do multi tenancy on standard installs.

I am not using autodiscover in any capacity. Each time a client sets up a device they simply manually enter the server address. No autodiscover nasty messages, it just works for everything except Outlook on Windows.

My UCC SSL cert is configured as follows.

DNS Name=mail.domain.com
DNS Name=www.mail.domain.com
DNS Name=domain.local
DNS Name=SERVER-01
DNS Name=SERVER-01.domain.local

OutlookAnywhere is enabled with URL mail.domain.com and basic authentication.

Both the domain controller and exchange server are running Server 2008 R2 with all updates and patches installed.

I would most sincerely appreciate any insight you might have. Thank you very much in advance.

You put in the RPC proxy settings prior to doing the checkname in the Outlook client?

Also are the people entering the details on the local domain or external? I would check if one or the other works first. I assume as you are talking about mobile devices working you have external connectivity enabled on mail.vhsli.com
