Deleted emails reappearing (iPad)

Whatever I have done I haven't been able to overcome this problem. All deleted emails reappear after few seconds. I have seen that this is not just my problem. In addition, with other phones/apps there are no suche problems so this IS an Apple related problem.

Has ANYBODY found a sustainable solution to this problem.

I have tried all the suggested solutions - including;

a) Removing and reinstalling all email accounts

b) Switching off iPad email syncing and switching on again

c) Restarting iPad

d) Etc. etc.

Couple of months ago things worked better but now ALL deleted emails reappear again, This is really frustrating - really tiring.

Hasn't anybody found a SUSTAINABLE solution to this problem.
