I have an iPad 2, running iOs5.0.1.
From time to time since installing iOs5 Mail stops working. Running an Exchange server.
I have tried stopping app, shutting down iPad, turning off networks and wifi and turning back on in all combinations but no joy.
I tried deleting all mail accounts and re-entering but no joy.
When in 3G mode it just says "connecting"....
When in wifi it says "Checking for mail"....
But does neither.
If I leave it off for a while (hours) then turn back on it seems to start working again but will then stop again.
