The last couple days, we have had several users with approved mobile devices get quarantined. The users are using the Outlook for iOS and Android app. So far, all of the devices experiencing the problem are iOS.
For example, a user will have an iOS device that has been connected for months. The mobile device will have it's last sync be at 11:13 AM.
The user then has a new mobile device connect to the system at 11:16 AM. Their phone, which has not changed, won't receive mail until I approve the new device and remove it from quarantine. Their account then has two mobile devices registered. The first appears dead with the last sync at 11:13 AM. The second device works fine going forward.
The user has done nothing to cause the change. It does not appear any iOS updates were installed, or Outlook app updates were installed.
What causes this, and how can I prevent it going forward?
