I have a exchange 2013 server running on server 2012. The SSL certificate from Comodo expired two days ago. We purchased a 3 year multi site certificate from Godaddy. I went through the process of creating the CSR, putting that into Godaddy's CSR request entry form and have received my certificate. I installed the intermediary certificate and see Godaddy certificate there.
I then go to EAC and complete the CSR and import the certificate. I then assigned the services IIS, SMTP, POP, IMAP to the certificate.
I have also looked at IIS manager to verify that IIS is using the correct certificate. The bindings.
However, when I go to the web site for our OWA, the old expired certificate is still there. I have been fighting with this for 12 hours now and would appreciate any help I can get.
Do you mean in IIS?
You can delete the expired certificate.
