Yesterday, Microsoft released a PowerShell script on the Microsoft Exchange support engineer's GitHub repository named Test-ProxyLogon.ps1 to automate these tasks for the administrator.

As you can see, I have created a simple four-line PowerShell script. This script's last line calls a function called Do-Something. That function creates a variable named A and sets it equal to 1234.

One of the best new features in PowerShell 7 is the ability to perform parallel execution of script blocks, which can drastically reduce the amount of time it takes to process ForEach-Object loops.
