In Exchange Server, if you need to do some maintenance work on a node and need to stop the services, restart the server, or shut down the server, it’s important to set the Exchange Server in maintenance mode. This allows you to stop and start the server with no impact. In the Exchange Server, the StartDagServerMaintenance.ps1 script is used to run various commands to put the Exchange server in maintenance mode. However, sometimes, when running the script, you may get the following error:
