How do I get rid of certificate pop-up in Outlook Anywhere while downloading OAB

I have 2 webservers for our OWA in Ex2007, (internal) and (external).

I have a certificate on our external webserver - "wmail.jetpak.com" which works fine.
(Ex2007 handles mail for jetpak.se, .dk, .no, .com, .org and.fi).
I created a dns-record for autodiscover.jetpak.se initially (just for test.) Now I can download the OAB externally (using - Test E-MailAutoConfiguration) but i get up warning saying
"security alert  - autodiscover.jetpak.se"
"the name on the security certificate is invalid or does not match the name of the site".

This is because the servername and the certificate is wmail.jetpak.com but autodiscover uses autodiscover.jetpak.se. Is there a way to change the autodiscover URL for the external site to wmail.jetpak.com/autodiscover/autodiscover.xml instead of autodiscover.jetpak.se/autodiscover/autodiscover.xml  for all "external" connections?


Watch Question

Hi, you can get rid of the certificate warning by installing SAN (UCC) certificate on your Exchange 2007.

Certificate Use in Exchange Server 2007

And regards to changing the External URL, you cannot change the External URL for Autodiscover, instead you can create a SRV record (if do not have plans for a SAN cert) which includes "autodiscover.jetpak.se". Check out the article which gives you a detailed explanation of the way Autodiscover can be confirgured externally -> http://technet.microsoft.com/en-us/library/bb332063.aspx

Thank you, I used the SRV record for _autodiscover on my external DNS. Really easy to do.
