Outlook 2010 hangs when trying to 'save as'

Hi Guys,

Just setup a new Win7 client / office 2010.

Configured libraries to include users home folder on server as well as other network locations.

All running fine except when the user tries to save an email. Once the explorer window opens to browse to location to save the email....Outlook hangs and I have to end task.

Same process works fine via Word 2010.

Any ideas?
