Our Exchange UCC cert (Multiple alternative names are included in the cert) is going to be expired in 15 days but I have renewed & installed the new cert on server & also assigned services like IIS,POP,IMAP & SMTP to it.
But that old certificate is still valid & I can see IIS,POP,IMAP & SMTP services also still checked in that certificate & can't deselect those services from that certificate.
I checked by accessing ECP console & found the new SSL certificate over there (In address bar) but in SMTP receive logs I can still see the OLD cert is in used.
How can I fix this? what will happen when my OLD cert is expired in this scenario?
Thanks in advance.
