The icons at the bottom of my emails have disappeared.
So when i go into an email - I cannot reply, forward, delete or add event?
Reboot your phone( Press the Home and power button until you see the apple logo).
IF what Mo-BEn suggested doesn't work - close out of the app, double tap the home screen - find the mail app hold down on it until it wiggles and close it.
and then do a reboot.
This solved my problem...
