Have an SBS 2011 server that has started issuing Event 25 warnings for soon to be expiring certificates.
I have a 3rd party UCC certificate installed (GoDaddy) that is not due for renewal for another year so that is good. Based on the Exchange Management console (EMC) the GoDaddy cert is installed for IMAP, POP, SMTP and IIS services.
It seems the original self signed certificates are expiring. I assume these were generated during server set up. Listed services in EMC for these self signed certs are IMAP, POP, and SMTP.
Can I just remove these self signed certificates from EMC, or are they still needed, even though I have a 3rd party cert?
Is it safer just to go into the certificates MMC for the local computer and "Disable all purposes for this certificate"?
