Hi @Microsoft Q & A ,

Is it a suddenly occurred issue? If so, have you made any changes to the Exchange organization right prior to the occurrence of this issue?

Please run the command below to check the service status on the server and see if there's any service needs to be started:

Test-servicehealth -server <ServerIdentity>

It's also recommended to run the HealthChecker script to check if the Exchange server is missing any CU or SUs.

In case the error persists, I'd suggest also having a look at the Event Viewer and see if there's any potentially relevant event recorded out there.
