I need to renew some certificates on one of our CUC clusters, on both the Pub\Sub the IMAP SSL certificates are expiring. I can't find the procedures for renewing this type of cerification on the CUC nodes. Can someone share the process. From what I can tell the IMAP certificate is used to secure email from a third party client like Microsoft. Do this certificate need to be renewed on the email server and uploaded to CUC. Any assistance would be greatly appreciated.
