This is the error msg I get when trying to open Outlook when I am remote . This happens to all of my remote users.  This happens after you VPN in and open Outlook. Once you hit OK and Outlook works fine.

That's because your certificate is named srvexchange and not mail.yourdomain.com

Either regenerate your self signed certificate with the correct name in it or buy a 3rd party SSL certificate and install that instead.

What version of Exchange and is it part of SBS?

Thanks Alan, that is a good tip. It is Exchange 2007 and it is on server 2003-R2.

Okay - not a problem.

With Exchange 2007 you really need a SAN / UCC certificate to make all the features of Exchange work easily.  It can be done without - but I'm not aware of the settings to tweak to get that working.

If you get a SAN / UCC certificate , please make sure you add the following names:

mail.domain.com
autodiscover.domain.com
srvexchange.internaldomain.local
srvexchange

Cheapest place is probably GoDaddy or a GoDaddy Reseller account might be cheaper still.

If you don't want to buy a certificate - then you can install the Windows 2003 certificate Services and issue your own certificate (single name).
