New mobile iOS device not quarantined

Question

Hi Guys,&nbsp;Need some advise or assistance. Looked online and I could not find any info in relation to this exact issue. We have a user who had her old phone quarantined in O365. It was unblocked and access was granted to her mobile device. 1 week later on the client has changed her mobile device and she managed to get her email setup on Outlook. Her new device was not quarantined.&nbsp;&nbsp;Can anyone assist? I had thought all new devices are quarantined and its device level not user account level.&nbsp;RegardsAaron

The default setting is to allow all devices, you must change it to quarantine if you don't want automatic approval.

VasilMichev&nbsp;&nbsp;Quarantine has been enabled for the tenant. The user's old device was&nbsp;quarantined and then released, so when they had a new device they expected the same behaviour - however the new device never got&nbsp;quarantined and the user was able to login to Outlook client to access emails.

Perhaps there's a device access rule in place? Hard to tell without being able to see your setup. In any case, you can easily test it with a spare device.

VasilMichev&nbsp;&nbsp;I believe this is possible there might be a device rule. How can i check that if you do not mind me asking?&nbsp;Another client with the same setup on their O365 estate had the same issue. The client device was initially quarantined upon changing his mobile device to a new Android device he was able to setup his O365 account with no restrictions on the new device.&nbsp;Thanks in advance

Are all these cases using the Outlook app?&nbsp;
