Autodiscover is working as expected - ie on most devices all you are prompted for is the email address and password. It assumes that the email address matches your logon name, but in some places this is not the case.
- Email addresses where I work are firstname.lastname@domain.com
- UPN are ABC123@domain.com
This means when devices try to autodiscover it fails (windows phone devices are OK as they actually ask for the username AND the email address). iOS and Android and Outlook 2010 just prompt for email address and password.
Is there any way to get around this? I have been advised that changing the logon names for users is not an option so there is no way to get the UPN to match their email address :(
I have thought about adding ABC123@domain.com as a SECONDARY address for users - would this be enough for autodiscover to work, or does it only work off the primary SMTP address?
