Testing the New Exchange Online REST-based PowerShell Cmdlets

Nine new REST-based PowerShell cmdlets are available for Exchange Online. They offer the prospect of better performance and reliability. Here are the code samples we used to test the new cmdlets for a theater session delivered at the Microsoft Ignite 2019 conference. Anyone wanting to explore the new cmdlets can use these examples to get going.
