VasilMichev I appreciate your valuable time in responding to my questions. We do have conditinal access feature. Our Application is registered to run as background service or daemon without a signed-in user. The application is accessed from AWS cloud through Oauth2.0 authentication. Can conditional access be still applied?

Conditional access doesnt apply to application logins, that's different from "user" access. Depending on the protocol your app is using, you might be able to restrict it via Client Access Rules: https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/client-access-rules/client-access-rules

VasilMichev Thanks Vasil , I too found the same solution. Due to some reason, our team is not ready apply access rules at exchange level. Do we have any other alternative?

  Nothing within O365, you can certainly add some restrictions in the app itself though.
