# Basic Troubleshooting for Gmail Mobile Email Setup

When a business mailbox fails in the Gmail app, test the account and settings systematically.

## Check the Basics

- Confirm the mailbox works in webmail.
- Re-enter the full email address as username.
- Verify the password by logging into webmail.
- Check incoming and outgoing server names.
- Ensure outgoing authentication is enabled.
- Try mobile data and Wi-Fi separately.

## Re-add the Account

1. Remove the incorrectly configured account from the Gmail app.
2. Restart the device.
3. Add it again using manual IMAP settings.
4. Send a message to an external address and reply back.

## Need Help?
