How to unassign self-signed cert from SMTP on Exchange 2010?

  • 772

We have a GoDaddy wildcard certificate that we have installed into Exchange 2010 and is successfully used on IIS connections for OWA.

We have assigned this certificate to the SMTP Service as well as IIS, but that doesn't seem to have unassigned the default self-signed certificate.

The self-signed certificate is already assigned to SMTP, IMAP and POP (we can't use the wildcard certificate for IMAP and POP due to it being a wildcard). Is it possible to unassign a self-signed certificate from just the SMTP service?

The only documentation I've found relates to removing a certificate completely.

    You can do this with Enable-ExchangeCertificate in the EMS by specifying None for that certificate.
