We recently installed Exchange 2007 SP1 on a Windows 2008 Server. We have a problem opening the Pop3 and IMAP access for the users. All users have the Pop3 and Imap enabled. The POP3 and Imap services are running, but after the user authentication the pop3 server application crashes.It seems to be a Schema issue somewhere. Does anyone have a solution for this?The following error report is produced by Windows:----------------------------------------------------------------------- Error Report

Hi Michael, Re-run the Setup /PrepareSchema from Exchange 2007 SP1 setup. If something is broken then setup imports it back then verify if it resolves.

Amit, 'thanks you for your reply, but unfortunatly this didn't solve the problem. We are still getting the same error message.
