Using Exchange 2013 CU4.
We have one Digicert certificate for SMTP, IIS and IMAP that expires in a couple of days. We have already installed the new Digicert certificate for the same Services and it did prompt us to overwrite the existing SMTP certificate during installation. We have not restarted the server or any transport services.
We have done some research but have read different methods of removal of old certificate (EAC versus Shell)
What are the proper steps to remove the expiring certificate, including service restarts, etc.?
Thank you!
