We have recently migrated from on-premise Exchange 2016 to hybrid with Exchange 2016 server used primarily for management. I have been interested in switching from a commercial SAN certificate to LetsEncrypt, but the idea of having my event logs perpetually full of 12017 and 12018 events due to Lets Encrypt's 90 day certs has made that unattractive. Does Exchange 2019 behave any better in regards to how frequently it complains about certificates expiring 90 days in the future?
