I just migrated from Exchange 2003 to Exchange 2010 and I have some issues. One main problem is the global address list. Our oultook clients are all 2003 versions. What seems to be happening is that the global list is not populating out correctly or Outlook 2003 is still trying to use the "remembered" addresses and not going by the new correct address. Is there a easy way to force the outlook clients to refresh the contact list or just delete the remembered list out so they have to go into the global list and click on the name?? Any help on this and basic exchange 2010 knowledge would be greatly appreciated. thanks.
