I renewed a GoDaddy SAN cert for my Exchange 2007 server. Quick history of company – original email domain was domain1.com, but then, after they booted the founder, they changed the default email domain to domain2.com. I renewed the SAN cert with the same names as the original. Now, when users are outside the office, it gives a site mismatch error on the cert, but does say the cert is valid at least. What is weird, is that the site is showing autodiscover.domain2.com, but everything I see in the web services stuff shows that the external fqdn is mail.domain1.com – I can’t figure out where the autodiscover.domain2.com is coming from. Every article I’ve read talks about setting the –AutoDiscoverInternalUri , but how is that autodiscover.domain2.com coming into it? Thanks!
Ok, a little more background. It only happens externally, and from what I've read, it's because the primary SMTP domain has changed not too long ago - this is where the autodiscover.domain2.com is coming from, but the cert is still for autodiscover and mail.domain1.com. What's the best way around this other than new certificate? Thanks!

Hi,
What you could do is implement autodiscover redirect, this will require an additional external IP-address but let's you redirect all request to domain2 to domain1. The best option although in this case is renewing the certificate.
For more information about redirecten see this page:
