Hi, I can confirm that there is a problem with iOS devices there.
Unfortunately I don't have direct access to the devices. The users
reported that email were not working for some days already. After
rollback to Horde_ActiveSync 2.37.1 the problem has gone. None of the
9 Android devices had a problem but 3 out of 3 iOS devices.
