Hi

I have a mixed 2010 - 2013 environment and things are almost working as expected. 

Right now I have 3 mailboxes in 2013, but if I try to create a new Outlook with one of those mailboxes I get the "cannot open your default e-mail folders".

If I log on to a pc with that user, Outlook finds the mailbox without any problems.

Why does it fail when I try to create a profile on another users login? It seems that it resolves to the old CAS array (RpcClientAccessServer). Even if I try to repair the Outlook profile it resolves the wrong (2010) CAS array.

Any ideas?

Hi,

According to your description, I notice that the problematic account could configure Outlook profile with new PC, it indicate that Exchange server works fine with autodiscover service, outlook anywhere and etc.

For this issue, please ensure the configuration for Outlook profile also check the URL by returns for Exchange server.

By the way, try to re-create a profile for testing.

Hi

Thats the problem. When we create the new profiles (logged in as another user) it resolves the server to the "cas-array name". outlook.domain.com and not the 2013 format.

If I then do a "Repair" on the profile it resolves correct and works.

All this is only a problem when you are logged in as another users. They want to open a shared mailbox in its own profile and they have the password.

I am able to reproduce this in a clean lab, so it is not only for that customer.
