how to block the Outlook desktop app while allow them use the Outlook On the Web (OWA)

I want to block users access to outlook from Outlook Desktop Application but let them access outlook from Outlook on the web (OWA) to improve security.

 

Is there someone who knows how to achieve the goal?

Thanks in advance.

      Any suggestion about how to block the desktop clients only on unmanaged devices?
      I intend to block Outlook only, not the other O365 Apps.
      Thanks!
      • Hi

        You could try to target Exchange online as the cloud app and as client app conditions the mobile and desktop clients apps and configure it on block (exclude compliant devices)

        Just curious but why only blocking outlook? 🙂
