I have upgraded a Win 7 computer from Outlook 2007 to Outlook 2010 in an Office365 environment. All the folders are synced and everything works fine except Contacts. When I go to view the Contacts, there are none and I notice kind of an orange progress bar moving as if Outlook is thinking. FYI, it's not actually a progress bar with a begging and end...just not sure how to best describe. This happens every time I click on Contacts.
I know there are contacts in this folder, because I can see the number of items (3526). This user has a lot of contacts. I am also able to change the view of the Contacts folder and I then am able to see all the contacts without any problem. However, if I click on to another folder, the Inbox for example, and then click back on contacts, I'm back to square one.
