I've got an annoying problem. We've got terminal services 2008 running at the moment and Outlook is setup on there. We have Open License, so plenty of licenses to go around.
However, there's on user mailbox when we log onto their profile and try to load Outlook it won't configure it as it keeps asking us to enter their username/password (as shown in the photo). The mailbox is working, it can be accessed via OWA so we know it's not password related. But for some odd reason, it won't allow us to configure the mailbox to use on terminal services. All other mailboxes can be created without any issues.
Any ideas where I can start looking?
