I keep getting a username and password prompt when setting up a new Outlook Profile on a workstation on the domain.
This happens to all workstations, Windows 7, vista and XP.
Exchange is a brand new 2013 server. I can access mailbox when inserting credentials but this should not happen as the mailbox is associated with an AD account and logged on as that users.
AD was migrated from Server 2003 to 2012
