Security Certificate that Cannot be Verrified

[wwwKris]

Hi There, I receive a message each time I start Outlook stating: "The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect. Do you want to continue using this server?" I have checked the security certificate and it is for my hosting company. Is there somewhere in Outlook that I can specify this certificate as "trusted" so that the message will not appear? Thanks, Kris
