Internet Security Warning (for Outlook)

[nolacane]

I recently started getting a pop up window everytime I open Outlook.



The window of the pop up says
"Internet Security Warning"
and the text of the message says
"The server you are connected to is using a security certificate the could not be verified. The certificate's CN name does not match the passed value. Do you want to continue using this server?....Yes/No"

I always select YES, otherwise I cannot send/receive email.

I did not change any settings to prompt this message. Any ideas on why this happened and how to remove this message everytime I open Outlook.

Not sure if this has anything to do with Norton Antivirus/Internet Security which I have.

Thanks
