I've a problem applying a new SHA2 Cert (from 123-Reg) to Exchange 2010
I created the request via the Certificate MMC as a custom request because this SBS 2011 server is SHA1 by default. Right clicked the Certs and installed both the Intermediate and the actual cert for the host mail.zyx.com.
When I looked in the EMC I didn't have the option to complete the Cert request, so I looked in IIS, the option was there and it completed as expected.
When I opened EMC to assign the Cert to the services SMTP etc, the Certificate page didn't load and generated error object get exchange certificates not found. upon running Get-ExchangeCertificate from powershell the same error is displayed.
I could assign the new cert to the default web site via ISS, which took care of OWA etc but still not the SMTP services etc
I found that if I remove the new cert from IIS - the EMC worked again and the old certs are shown as normal..
hope that's enough info, any help or ideas would be appreciated?
