Outbox mail not sending mac

The frustration of not being able to send outbox mail on a Mac! Don't worry, I'm here to help you troubleshoot the issue.

Here are some common reasons why your outbox mail might not be sending on a Mac:

  1. Internet connection issues: Check your internet connection to ensure it's stable and working properly. Restart your router or modem if necessary.
  2. Mail app settings: Ensure that your Mail app is set to send emails using your preferred email account. Go to Mail > Preferences > Accounts, and select your email account. Make sure the "Outgoing Mail Server" is set correctly.
  3. SMTP settings: Verify that your SMTP settings are correct. Go to Mail > Preferences > Accounts > [Your Email Account] > Advanced > SMTP. Ensure that the "Server" field is filled in correctly, and the "Port" is set to the correct value (usually 587 or 25).
  4. Authentication issues: Check your email account settings to ensure that you're using the correct username and password. If you're using two-factor authentication (2FA), ensure that you've enabled it in your email account settings.
  5. Mail app cache issues: Try clearing the Mail app cache by going to Mail > Preferences > General > Reset Mailbox Data.
  6. Outbox folder issues: Sometimes, the outbox folder can become corrupted. Try moving all emails from the outbox folder to the sent folder, and then empty the outbox folder.
  7. Mail app updates: Ensure that your Mail app is up to date. Go to the App Store and check for updates.
  8. System configuration issues: If none of the above steps work, try resetting your System Configuration by going to System Preferences > Users & Groups > Login Items, and then restarting your Mac.

To troubleshoot the issue further, you can try the following:

  1. Check your email account's web interface to see if the emails are being sent successfully.
  2. Try sending an email using a different email client or app to rule out Mail app-specific issues.
  3. Check your Mac's system logs for any errors related to the Mail app.

If none of these steps resolve the issue, you may want to consider seeking assistance from Apple Support or your email provider's support team.
