Our domain wildcard certificate is about to expire on 04/06/2022 and we are receiving event logs notifying that the certificate will expire soon. But we had no crash so far. The other certificates (created by Exchange on setup) are still valid for a long period of time. The expiry notifications about our certificate were already present as we installed the SU last tuesday. Server runs fine at the moment.
Should we expect failure of the server soon, or do we have some time to renew our certificate in the next days?
Is there anything we should keep in mind this time when we change the certificate? Could we trigger that crash if we replace the certificate with a new one, or should we wait for a fix from MS (but then, this fix should arrive before 04/06/2022)..?
