Get a list of all Dynamic Device/user Groups in Azure AD and their rules

A quick note, this requires the newer AzureAdPreview module, as some of the fields retrieved by the Get-AzureADMSGroup command are not present in the current AzureAd module.

# script to get a list of all Azure AD DYnamic Groups and rules.
# This requires the azureadpreview module
# install-module azureadpreview
# you will need to remove the regular azuread module if you have in installed first!
