Small update here. We deployed CU14 in our first environments (after a test install), no issues during installation and with functions.
> Both on Win2022 and Win2019.
Post install, we run (ofc) the HealthChecker. All green.
The only thing I see on all servers now with the last Healtchchecker that there is authentication setting on the IIS site, which is not supported (bottom warning). This also happens now on servers BEFORE the upgrade. Not sure if this is a Healthchecker bug, or something to look into. No issues with devices, also no weird config has ever been made. Only settings changes post install: logon domain settings in the OWA virtual directory, via ECP. No custom IIS tricks or whatever.
