Security Certificate error in Outllook 2010.

Not open for further replies.


I am running Exchange 2007 on a SBS 2008 server and I am using a self-signed SSL certificate for Outlook Anywhere.

I recently set up a user with Office 2010 and his Outlook 2010 keeps showing a certificate error every time the program is launched.

I have modified the internal URI to point to the certificate's common name and still get the same error.

Any thoughts?...
