Outlook 2010 connectivity to exchange 2013

We have recently upgraded to exchange 2013 running on server 2012 R2.
I have 2 identical exchange servers for high availability.

I am able to manually set the outlook profile correctly and successfully connect to Exchange.
When I exit Outlook and try to restart it outlook fails to connect.
When I go back and look at the profile some thing has changed the profile some times the authentication method has changed some times the proxy server name has changed.
I have to go back and remove the profile and create a new profile, and the user is able to log in again successfully.
The work stations are running windows 7 processional 64 bit.
Any ideas will be greatly appreciated.

That is looking like Autodiscover issues, and possibly that you don't have the URLs configured correctly within Exchange.

With Exchange 2013, Autodiscover is not optional. You must have it working correctly.
That means all URLs configured correctly, valid SSL certificates (Self signed is not supported).

The authentication method is all configured via Autodiscover, so will follow what you have set on the Outlook Anywhere configuration. If the two servers are on the same site, then they need to be identical. Same URls configured everywhere.

That is what I had thought but prior to beginning the process of synching the servers I wanted additional confirmation.
