We are seeing issues after enabling Security Defaults where activesync clients get quarantined in Exchange Online and cannot be approved. O365 Support have been unable to tell us why or fix it.
Has anyone seen this or know how to resolve? Problem clients are all iOS using the native mail app.
In EXO PS using get-mobiledevice I can see:
DeviceAccessState : Quarantined
DeviceAccessStateReason : AadBlockDueToAccessPolicy
We have no activesync policy to quarantine devices. Some work fine, some get blocked.

Security defaults block legacy auth, which is the most likely reason here.
