+Please note that we will begin to deprecate this module when the functionality of this module is migrated to the newer [Azure Active Directory PowerShell V2 Module](https://docs.microsoft.com/en-us/powershell/azuread/v2/azureactivedirectory). We advise customers who are creating new PowerShell scripts to use the newer module instead of this module.
