Action: Block all devices except Outlook for iOS and Android and Exchange ActiveSync clients on Windows devices  - If your organization has standardized on Outlook for iOS and Android and Windows devices as the only approved apps for accessing messaging data on mobile devices, you can define a default block rule and configure an allow rule for Outlook using the following commands in Windows PowerShell. This configuration prevents any non-Windows Exchange ActiveSync (EAS) native app from connecting and only allows Outlook for iOS and Android devices to connect. To do so, see Option 1 in Enabling Outlook for iOS and Android in Exchange Online. Learn more at Outlook for iOS and Android.
