As an Exchange Admin, you might be looking after 1 server or several hundred.
Sometime after a reboot you might notice that some of the services don’t start. It is a daunting task to go manually start them all 1 at a time.
A simple way is to run the following command from an elevated PowerShell Window:
- Get-Service *Exchange* | Start-Service
Some services like the Transport and Unified Messaging Services take a bit longer to start but the window will echo the starting of all services.
Hope it helps.
