We're in the process of upgrading our company's office professional suite from 2003 to 2010. I've installed office 2010 on several machines and everything works fine except for one user. Regardless of the machine the user attempts to access outlook 2010 from, it becomes unresponsive at the "Loading Profile" page. I also attempted to access their mailbox using Office Pro 2013 with the same failing result (tried both in safe mode as well). The only version of Outlook that seems to work for the user is 2003.
All other users that have attempted to connect via Outlook 2010 and 2013 have been successful. Any ideas as to what might be causing the issue?
