Hello! We are currently attempting to deploy a massive amount of iOS Based Devices for O365-GCC. MS Authenticator and Outlook for iOS work perfectly together now that Modern Auth is seamless for us, however, I need to be able to target Outlook for iOS and Apple Native Mail; and block all other clients using the Device Access Rules.
We currently have the default as block, access for Outlook for iOS enabled, but what User Agent String do I use to target Apple Native Mail specifically? I would consider a Device Type Rule (such as, allow iOS), but I don't want any other third party iOS Agents to be able to use it.
