I am trying to configure outlook 2010 client to connect to exchange 2013 mailbox account. The domain account is a tenant domain on my exchange 2013 server. I have added the internal DNS A record to point to my exchange 2013 server but it still says:
The name cannot be resolved. The connection to the Microsoft exchange server is unavailable. Outlook must be online or connected to complete this action.
I am able to connect internally and externally to OWA via the web URL without a problem: https://mail.mydomain.com/owa
Things I have done:
I have made sure the workstation is set to the correct time as the server.
I can ping mail.mydomain.com and get the correct exchange 2013 server ip address
Any other ideas?
