I was working on a lab for a customer, installing Exchange 2013, when I noticed my script needed some TLC. I updated some code, added some error handling, corrected some syntax and worked on the menu. The new version of the script can be found HERE. If you like the script, please make sure to give it 5 stars. This script is around seven years old now and will probably get one or two more updates, but that is it.
I also have scripts for Exchange 2016 and Exchange 2019. These scripts will eventually make it over to GitHub as Microsoft also makes the move in that direction. In the meantime, feel free to leave feedback and vote for the scripts so I know if I am making the write scripts for the community. Enjoy!
