I have configured by domain controller with a group policy to "Automatically configure profile based on Active Directory Primary SMTP address". The Autodiscover is working as expected and it connects to my hosted Exchange server.
The issue is that the cached user name is being picked up from the domain, in the following format user@domain.local
Is it possible to control which user name is being passed, so that I can pass a user name in the correct format, which in this case is the primary SMTP address.
PS. I don't want to use a UPN suffix. I want to be able to specify the email logon name independently of changing AD setting.
Thanks,
