Hey all. I'm having a problem creating an Outlook profile on a domain joined computer. It's not the domain Exchange is installed in, but another completely separate domain. If I login locally and create the profile, I am prompted for authentication and after I enter the correct domain/user info, the profile is created with no issues. If I'm logged in to the problem domain, I am never prompted and profile creation fails with an error about not resolving the username. It looks like it's failing on the authentication step.

I'm assuming the user is logged into a domain (not just ours but any domain) and is getting the internal authentication setting which says to use NTLM. This fails to create the profile because the logged in user is in a different domain than the mailbox they are trying to use. When I try when logged in locally, I assume it's using the external setting which says to use negotiate.

I cannot manually adjust the authentication setting because I can't even create the profile. If I manually create it and specify the correct server name GUID, as well as everything else, I can change authentication to basic and only then does it work on the domain joined computer. Any ideas how I can get this to work? Is there a way to force the computer to use basic regardless of what autodiscover tells it?

Thanks,
Tim

Hi,

I just wanted to know that is your exchange server is accessible from external world? if yes then the system where you configured the account does have internet connectivity? and if your exchange server is not accessible from external world the in you local DNS server where the user log in, in that domain create a MX record. and then check....

Hi Tim,

I recommend you refer to the following similar thread :

Using Outlook Anywhere on a PC with a different domain

Try to install the exchange domain certificate to the root store.

Best regards,
