Client using Outlook 2007, Exchange 2007 Certificate Error on Cisco Router based network

If the Outlook 2007 clients and Exchange Server in your organisation are on a different subnets and router connecting these subnet is listening port 443 , the auto discover mode of Outlook 2007 and Exchange 2007 may fail because of DNS name resolution problem. Auto discover service allows your Outlook 2007 clients to retrieve the URLs that it needs to gain access to the new web services offered by Exchange 2007.
Cause of this failure is certification mismatch that outlook use to create secure connection channel between client and server.
Use "no ip http secure-server" command on Cisco router, to prevent router from listening https port.

  1. I seldom use MS Outlook. And once something happened with tool. It turned out that my outlook password was crashed. Fortunately I entered in the Google and observed there - outlook user forgot pst password. The application helped me for seconds and free of charge as I bore in mind. The utility showed me how it retrieved forgotten or lost passwords for Microsoft Outlook email client or for files with *.pst extension.
