Hi,



Our SSL certificate is expired today, but we renewed it two days ago.



Today, Outlook pops up a security warning for all user saying "The security certificate has expired or is not yet valid." I clicked the "View Certificate" button, it shows the old certificate.



I checked the local computer certificate store and found the old certificate is in the trusted store, I removed it, but it didn't help. Outlook still remembered the old certificate.



OWA is fine and the certificate is updated.



Need help!



Thanks in advance!
