mY ipad 2 seems to have lost my previous emails and my saved emails in my reference folder have disappeared too.They briefly appeared for a few seconds then went again.I can send myself a test email but the others did not appear again.I have tried one or two suggestions from previous posts on this problem such as switching off and jiggling but am at a loss what to do next.Also.where is the best place for my wi fi router as sometimes my connection is a bit erratic.At present it is on a shelf in the centre of my room unobstructedAny help gratefully received.
