Microsoft Exchange 2013 PowerShell Useful Scripts

There’s some basic tasks which are good to automate, to save you some time, you can configure them to run as a scheduled task.

First step is to create a user account to run the scripts, this account should have access to change Exchange and change Active Directory, lets call the account: exchangeserviceuser.
