Do others have to keep deleting their email account and then re-add over and over?

This seems to be the only fix for the error message telling me I cannot get mail or send it.

why do I have to keep doing this step and then after a few days it happens all over again with

the same error message: CANNOT GET MAIL.

IS THERE A LOGICAL REASON WHY THIS HAPPENS WHEN I AM USING THE SAME WIFI

AND LOCATION? Would someone please confirm that I do not lose any files, contacts, or

emails when I have to keep doing that? Thank you so much!!!
