By default, the Microsoft Exchange 2007 IMAP service is Secure IMAP (sIMAP) running on port 993. If you have verified the user name andÂ password of journal account, IP of the mail server, and the IMAP service is running on the mail server, you might experience an invalid certificate issue. In this case, the RazorGate IMAP fetcher will display a login error message.
This issue might be caused by the security certificate used by the IMAP service, i.e., the Microsoft Internet Information Services' certificate, is invalid. For more information, see this external article regarding Exchange 2007 certificates and the Microsoft Support site's Outlook 2007 and Exchange 2007 Certificate Issue article.
