PowerShell: Assign Email Address to Environment Variable

Recently, we encountered a special situation where we needed to have an environment variable that consisted of the user's email address. That prompted me to write the following script that will do just that. The script needs to be executed as the user. I set it up in the logon script and hid the PowerShell script. This script was executed on Windows 10 machines, so I cannot guarantee it will execute on other OS versions.

NOTE: This script requires RSAT to be installed. in order to utilize the ActiveDirectory module.


You can get the script from here.

6:            This script will assign the user's email address to the environment variable EmailAddress.
