Enjoying the quiet here at the end of the week before the holidays, when out of the blue a user gets this message in Mail on their iPhone:
They're currently unable to send or receive emails from their phone. I've looked around at all of our settings, but we don't have two-factor enabled for anyone right now, so I'm stumped. I haven't heard reports from any other users (though a lot of them use the Outlook app), but I haven't changed any of our Exchange or Security setting in a few weeks, either, so I'm not sure what would have triggered this all of a sudden. Any thoughts before I open a support ticket?
Thanks. I checked the device quarantine and this users's device, along with several others, had managed to find their way into the quarantine. I used the PowerShell commands from your blog to verify that the user's device actually did get removed from the quarantine.
