Checkboxes Greyed Out When Managing Services for an Exchange 2013 SSL Certificate

When you are managing services for an Exchange Server 2013 SSL certificate via the Exchange Admin Center you may notice that the checkboxes for enabled services are greyed out and can’t be unticked.


Exchange 2013 will not allow you to disable/unassign an SSL certificate from a service that requires SSL. Instead, you should enable another SSL certificate to that service, which will automatically disable the existing one for you (for that specific service, not necessarily all services).

    I assigned a new SSL cert to the SMTP service on my Exchange 2013 server and got the prompt about overwriting the old one. However, the old cert is still bound to the SMTP service and I can’t uncheck the box. Do I need to reboot the server or can I just restart the SMTP service to unbind it?

    Hi Paul,

    I have one self-signed certificate that is assigned to services: IMAP,POP,IIS,SMTP. That’s fine.
    But, I have another certificate that I use to integrate skype_owa, and when I import it, automatically it is tied to IMAP,POP services, and I just want to let it assigned to none services.

    The following command didn’t work.
    Enable-ExchangeCertificate -Thumbprint C53154BF580C5ACC69253461CADFC82CFEFBDDB4 -Services None
