Exchange Email Synchronisation Reliability

And it does … less that an hour after enabling both wireless and mobile data together the ‘Sync Error’ is back on all of my Exchange accounts - around about once every couple of hours or so (sync is set at ‘Always Up To Date’ and I’ve had quite a few emails in today successfully, so its clearly not every time).
This does tend to suggest that the EAS sync process has a problem when there are two data networks available (wireless and mobile) and switching from one to another after, say a momentary dropout. If there is only one network available (i.e. mobile or wireless - it doesn’t matter which) then it does seem to be able to copy with a dropout unless it is too long - and perhaps that is why I got the ‘Connection Timeout’ message. @flypig does that give you enough to work on, or do you still need logs?
