We'd like to build a PowerApp to offer self service to our customers, one of the features we'd like is a test field where you can enter the email address (alias) of what you want, and we will dynamically look to see if its available or not. - currently the thought process is we will have to kick off a PowerShell script which calls the Get-Recipient Cmdlet, and do some funky stuff with the results (or hopefully none) - is there something we can utilize (or that is coming) to the MS Graph which will give us a better and faster solution?
