SYMPTOMS
When you restart an Exchange Server 5.5 computer which has Microsoft Outlook Web Access (OWA) installed on it, users may not be able to use that Exchange Server computer to log on to Microsoft Exchange 2000 mailboxes unless someone first uses that computer to log on to an Exchange Server 5.5 mailbox.

After you log on to an Exchange Server 5.5 mailbox, users can log on to Exchange 2000 mailboxes.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
