Hi Mike

I've recreated the account more times today than I can count (and
yesterday when I removed the account and even rebooted before
recreating it).  Unfortunately it means both the email clients on my
device are broken (the native Google one (not Gmail, the other one)
and Enhanced Email.  Enhanced Email is less broken, but doesn't allow
me to create contacts.

What I see on the device is that an initial sync is done but then the
contacts later disappear (and won't reappear unless I:
- turn off the sync,
- reprovision the device in the admin/activesync.php
- turn on the sync).

Then a short time later the contacts disappear again.

Oddly the calendar entries survive unless I add/change an event and
then they too disappear.  This was working, but I don't know when it
stopped as I've been working with the git install for a while now.
One of my users used to have a similar problem which I blamed on the
network, but it went away after they got a new device.

I would have thought more people with stock ASOP devices would have
this issue...
