  • Hi raminsr,

    What service did you assign to that cert? Was IIS included?

    Did you replace the old cert in IIS binding? 

    There are 2 different bindings in IIS for Exchange. The default web site and the backend. The backend should be using its own generated self-signed cert titled "Microsoft Exchange". This was created when Exchange was installed and generally speaking there should be no need to modify it. The default site should be bound to the 3rd party cert.

    And can you open Exchange Management Shell now? 

    Try to re-create virtual directories for ECP and OWA:

    Remove-OwaVirtualDirectory -Identity "adminsrv\owa (Default Web Site)"
    New-OwaVirtualDirectory -InternalUrl 'https://mail.domain.com/owa' -WebSiteName 'Default Web Site'

    Actually this Exchange Server Development forum is NOT for asking such questions, the previous TechNet Exchange forum has been migrated to Q&A forum, you can post your issues there for better support.
