delete email account from my iPad

Email accounts are set-up independently on each of your devices. Deletion or addition of an account will only affect the device upon which the change is made.

If you wish to delete your email account from your iPad, it can be removed from here:

Settings > Passwords & Accounts > [Your email account] > Delete Account

Hello,

The iPad is locked with Activation Lock. There is no way around unlocking Activation Lock without inserting the device’s associated Apple ID. If this is not an option you will have to find the original receipt for the device that clearly shows the serial number. Once you have this document you will need to take this document and iPad into an Apple retail location.
