Hey,
I have a problem with my Exchange 2019 server. After Friday I installed CU10 and immediately afterwards (run in cmd as admin) KB5004779. After the reboot, the Exchange services do not start automatically. Set it to auto-delayed and rebooted and it worked fine. When I start Exchange Administrative Center I get HTTP 500 error. When I start the Management Shell I also get an HTTP500 error (+ FullyQualifiedErrorId : WinRMHttpError,PSSessionOpenFailed) and it cannot connect. ExchangeInstallPath checked and in IIS PowerShell virtual directory. I can't find anything in the windows log that can help me. I've tried everything but can't get it to work. Can someone help me with this.
