LukasSMSFT I never had any crashes... - just asked what to do with our soon expiring certificate (04/06/2022). We had eventlog entries about expiring on 04/06/2022 BEFORE we installed the SU on tuesday. We had no crashes after the installation of the SU. I read in a german blog that expired certs. and soon-to-be-expired certs. *may* cause issues crashing the server. Also heard that one person encountered problems some days after the patch (not during the first days - strange!). To prevent our server running into such a situation, I asked for what to do... - yesterday, I decided to exchange our wildcard certificate with a new one. No problems so far, no more warnings in eventlog about cert. expiring. 🙂
Do you have any information what exactly is causing such crashes? What about
"SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}"Why is this mailbox involved?
