Mail app has crashed
The Mail app on my iPad mini has crashed and I want to uninstall it, reset iPad, and reinstall mail. Is uninstall the same as cancelling the mail app in settings?
iPad Mini, iOS 8.4.1
There is no need to uninstall it.
Try to reset your device. This won't delete your data stored on this device.
- Press and hold the Sleep/Wake button
- Press and hold on the Home button
- Keep holding both buttons until the display turns off and back on with Apple logo on it.
Alternatively, you may go to Settings - General - Reset - Reset All Settings

If this does not help, restore your device to factory settings. Note that this will erase the data from your device.
Take a look this Apple Support article: Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support.
