To automate the running of a Microsoft Exchange cmdlet in Scheduled Tasks (for instance) an additional parameter must be supplied along with -command when calling powershell from within a BAT file.

The syntax is:

powershell -PSConsoleFile "C:\\ExchangeServer\\bin\\exshell.psc1" -command ". 'exchange-cmdlet-here'"

Replace c:\\exchangeserver with your Exchange Server path.

For example you may with to test your replication health and output it to a text file for further processing:

powershell -PSConsoleFile "C:\\ExchangeServer\\bin\\exshell.psc1" -command ". 'Test-ReplicationHealth'" >c:\\SCRStatus.txt

It is always recommended to save your command to a BAT file and have scheduled tasks run this, instead of entering the command line as a Scheduled Tasks.
