SBS 2008 + Exchange Server 2007
Our self signed certificate expired a few weeks ago. I used the wizard in the SBS console to replace it. I noticed today that event 12016 is now being logged quite frequently. This says 'There is no valid SMTP TLs certificate for the FQDN of ouremaildomain.co.uk.
I am not aware that I ever created a certificate for that email domain. When I set up the server, I used a completely different domain ourofficedomain.co.uk because our primary domain is hosted elsewhere for our ecommerce store. I set up an mx record to point mail.ouremaildomain.co.uk to our sbsserver.
I think I need to do some housekeeping. I can see that there are 9 expired certificates. With these names "Sites", "remote.ourserverdomain.com" and "Server.ourdomain.local" Is it definitely ok to delete all expired certificates?
Do I need to create a new certificate for our email domain? or do I just need to make exchange aware of the one i created a few weeks ago? Funny... in the list of certicates, I can't see any certificate that was created recently
