We are migrating mailboxes from Exchange 2007 to 2010. Exchange 2007 still has Public folders, but our Exchange 2010 doesn't. Now I see in see that mailboxes that have been moved to Exchange 2010 still make contact to the old 2007 public folder.
The only way I have been able to fix this so far, is to recreate the Outlook profile on the client pc. Is there another way to fix this? We have thousands of clients, deleting all profiles would be horrible.
