Signing out of Mail on iPhone is a simple process that can be completed in just a few steps. It may be necessary to sign out of Mail for various reasons, such as troubleshooting issues, switching to a different account, or protecting privacy.
Signing out of Mail also helps to protect your privacy and security. When you are signed out of Mail, your email account is not accessible to anyone else who uses your iPhone. This can help to prevent unauthorized access to your email messages, contacts, and other sensitive information.
