I had this EXACT error during my migration from 5.5 to 2003.... I was also noticing that users on the 2003 environment could not view the address book... The fix for me was simple - - First, in ESM view the properties of the server where your OAB is located - Go to the Directory Access tab and verify your DC's that are listed are Global Catalog servers - If they are listed correctly (based on your environment) this indicates that the DC's most likely have not been rebooted since being set as Global Catalog servers... - ( I know this sounds a bit weird, and I did not agree with Microsoft Support at first) The GC DC's MUST be rebooted after set as a Global Catalog. A setting is not updated until a reboot occurs. - Reboot each GC DC (at separate intervals) - Once each GC DC is back up, rebuild the offline address book - Login to outlook and verify that you can view the Address Book and errors on the Exchange Server no longer appear... Hope this helps. Your users will not notice any outages during the reboot of the DC's. Keep in mind that my DC's are on separate servers from my Exchange Servers. Worked like a charm for me...

If you continue to get it, then my best guess would be that your Address Templates are either corrupt, deleted, or have a security issue. _____ From: Bruce J.
