Unable to delete Mail account under accounts

ER_Krishna,

We understand now that your mail account delete buttons are not working and it maybe because of Content & Privacy Restrictions being enabled. Go to Settings > Screen Time > Content & Privacy Restrictions > Account Changes needs to be set to Allow so that you can delete mail accounts. 

Use parental controls on your child's iPhone, iPad, and iPod touch

If you still have problems try to check to see if you have a configuration profile installed on your device removing the profile may allow removal of the email account. To remove a configuration profile from your iOS device go to Settings > General > Profiles & Device Management.
