Exchange 2010 MAPI security alert

Hi Experts,
I've recently installed and configured an Exchange 2010 server.  I've puchased a UCC certificate for autodiscover.outsidedomain.com and inbox.outsidedomain.com.   The internal server name is inbox.internal.local.  When employees first open outlook, they receive:

 "Security Alert: The Name of the Security Certificate Is Invalid or Does Not Match the Name of the Site"

I've created DNS records for inbox.outsidedomain.com on our internal DNS server to point to inbox.internal.local.  

I've also followed this guide with no success:  http://support.microsoft.com/kb/940726

Please help!

Thank you!

Hi there,

first of all, I suppose that clients are trying to access the site using "inbox.outsidedomain.com" as external url?

The SN of the certificate should indeed be "inbox.outsidedomain.com" (if that's your external url)
and as SAN's you should have the server's internal name, autodiscover.outsidedomain.com, and any other name on which the server should be available.

Hope this helps!

Greets,

Michael

Hi Michael,

The clients are indeed connecting to inbox.outsidedomain.com however the server is being resolved back to inbox.internal.local.

Would not adding inbox.internal.local to the unified communication certificate cause this error?

Basically, should I modify the cert to reflect:

inbox.outsidedomain.com
autodiscover.outsidedomain.com
inbox.internal.local

Thanks again.
