Outlook Certificate on Self Signed Certificate

Answers

  • Hi,

     

    As the article said, if you use Outlook 2007 running in Exchange 2007 and the client is in your domain, there is no any certificate warning. And I have tested this situation and it works fine.

     

    But since you use Outlook 2003, I doesn’t have this environment so you can check whether only Outlook 2003 clients have this issue.

     

    Hope it helps.

     

    Thanks

  • Since when did this issue start ?

    Was the certificate recently renwed ? I suspect it may be due to not being able to reach the root certificate authority.

    Please double click the certificate and check the certification path tab to see if the path is all the way up to root.

  • After investigating, Outlook 2007 SP2 will fix the issue.
