Experts Exchange connects you with the people and services you need so you can get back to work.

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 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?

You say you've added the A record. Have you also added the MX record?

Well the MX record is pointing to my spam filter IP address. So yes its created and configured properly.
