I have been having major problems getting an SSL certificate installed on my Exchange 2007 server. I have successfully installed a test, 90 day trial certificate from comodo and tested external OWA and Activesync with my mobile devices. However, since I also need internal DNS resolution, I purchased a UCC certificate. Now I can't seem to enable the certifcate in Exchange. I can enable it just fine for the services: POP, IMAP, and SMTP, however the service that I really need it for (IIS) returns an error.
When I enter this command in the managment shell:
Enable-ExchangeCertificate -thumbprint <thumbprint> -service IIS
I get this error:
Enable-ExchangeCertificate : An unexpected error occurred while the forms-based authentication settings for path /LM/W3SVC/1 were being modified. The error returned was 5506. At Line:1 char:27
I have contacted support at comodo, and searched EVERYWHERE online with no luck. I'm pretty sure it has something to do with one of my IIS7 virtual directories, but I cannot find the solution to this one. Any help would be GREATLY appreciated.
