I have Exchange 2010 installed and using Outlook 2007, no other Exchange servers in the domain. The Global Address List is not displaying the correct information. When I click on the Address Book Icon and choose to view All Users I can see the information I was hoping to see (Phone, email address, etc), but when I open a users entry (double click on it) form is blank. I have blown away the Outlook Profile on my PC and created a new on and when I do this, the GAL appears correctly with all of the information, but it will revert back (no specific time frame for this) to what I had described earlier. Any thoughts and where to start troubleshooting this?
Here is an update on this question. I neglected to indicate that I am using Cached mode for Outlook. I turned this off and the GAL is showing correctly again. I don't believe in coincidences, so this must be an issue with Cached mode in Outlook and Exchange 2010. Never had this issue in previous Exchange 2003 configurations and Outlook 2007.
