Exchange Email Distribution Email Groups Script Report – Know your recipients !!

Hi again,

One of the simplest things in Exchange, is to query email distribution groups from the GUI management console, or with one PowerShell command. So why bothering to blog or script about it?

Well, sometimes, you get a project to standardize mailing groups names, or to assign a manager to each mailing group so he can manage it.

Sometimes, you want to get an overall view (statistics) in nice format to present in the Exchange quarter meeting (i hope you have such meetings !) , or may be you want to find out which mailing groups are empty and need cleanup.

In all cases, you just need to run a script , identify where you stand in regards to mailing groups, and evaluate if there is something need to be done or not. Nothing can go bad if you have an overview script to generate such report at least once.

 Download Script

You can download the script from here

Running the Script from Exchange PowerShell Console Experience

You can schedule the script to run in a certain schedule and get nice email reports, or just run it directly without any switches from the Exchange PowerShell console from an account that is member of the Exchange View Only group.

You need only to modify the SMTP setting in the (Customize Script) section to receive the output email report.

The script when run form PowerShell Console, give you a nice and rich experience, where it will list the script description,  version , and will breakdown in real time every operation that is running and when possible, a progress bar for long running tasks.

Finally, the script will give you a timer with the time spent in certain tasks in a nice friendly way.
