Example Command(s):

Exchange 2007:
Enable-ExchangeCertificate -Thumbprint $THUMBPRINT -Services 'POP, IMAP, IIS, SMTP'

Exchange 2010 and 2013:
Enable-ExchangeCertificate -Thumbprint $THUMBPRINT -Services POP, IMAP, IIS, SMTP

You will need to replace $THUMBPRINT with the certificate thumbprint this can be found by viewing the certificate under the certificate details inside the Microsoft Management Console's Certificate Snap-in for the Local Computer account. Also, if you have existing services, you will need to re-list them upon entering the command.
