To enable a service on the cert, make sure you get the thumbprint of the cert which you can get by using the following command Get-exchangecertificate |fl  and then use the below command to assign a certificate.

Enable-ExchangeCertificate -Thumbprint E8C1BB735FA57C4E70988420CE247263AD92DC65 -Services "iis,imap,pop"

If you do SSL offloading then make sure you use the DoNotRequireSSL tag after the command look below for example

Enable-ExchangeCertificate -Thumbprint E8C1BB735FA57C4E70988420CE247263AD92DC65 -Services "iis,imap,pop" -DoNotRequireSsl
