I have an Exchange 2007 HMC deployment for which I'm testing Outlook Anywhere autodiscovery.
IIS is configured with an autodiscovery redirecting virtual directory, and the relevant websites are protected with a legitimate UC SSL certificate.
The problem in a nutshell is that Outlook 2007 displays a certificate mismatch warning (name on the certificate is invalid or does not match the name of the site) relating to autodiscover.[customerdomain].com. If accept the SSL warning, I then receive the expected warning about being redirected to a different url for autodiscovery and all is well.
The OA tests at https://www.testexchangeconnectivity.com/ do run successfully though. Going through the tests it performs, it also sees the certificate mismatch error but then proceeds to test with the http redirect method which successfully redirects to https://autodiscover.[serviceproviderdomain].com which is a SAN on my SSL certificate and tests out fine via a web browser.
I'm sure I'm missing something obvious - can anyone suggest where I'm going wrong? I can't accept letting users see the SSL warning.
Versions are Exchange 2007 SP2 on Windows 2008 Enterprise, and Outlook 2007 SP2 on a variety of different OS.
Thanks for your time,
