We have Exchange 2000 on Win2000 with AD. I have separate folders under "All Public Folders", i.e. Company Contacts, Vendors. When I rebuilt the Exchange Server, I moved these Public Folders onto my Personal Folders through Outlook. When I finish the Server built, I copied them back under the "All Public Folders". Now when you go to a contact in "Company Contacts", and look at that contact for them it should link to someone in the Vendors list, but error is: The name or distribution list has been deleted and is no longer a valid Address Book entry. How can I resolve this as there are so many linked contacts within the 2 Folders. Any help would be great. Thanks
