Apple mail not suggesting email address

Frustrating!

Apple Mail not suggesting email addresses can be due to several reasons. Here are some troubleshooting steps to help you resolve the issue:

  1. Check your Contacts: Ensure that your contacts are synced correctly with your Apple ID. Go to Settings > [your name] > iCloud > Contacts and make sure that Contacts is enabled.
  2. Update your Contacts app: Ensure that your Contacts app is up to date. Go to the App Store, search for Contacts, and update it if necessary.
  3. Check your email account settings: Verify that your email account settings are correct. Go to Mail > Preferences > Accounts, select your email account, and ensure that the "Suggest names while composing" option is enabled.
  4. Clear Mail's cache and data: Sometimes, clearing the cache and data of the Mail app can resolve the issue. Go to Settings > [your name] > Storage & iCloud Usage > Manage Storage > Mail, and swipe left on the Mail app to clear its cache and data.
  5. Reset your Mail app: Resetting the Mail app can also resolve the issue. Go to Settings > [your name] > Storage & iCloud Usage > Manage Storage > Mail, and swipe left on the Mail app to reset it.
  6. Check for conflicts with other apps: If you're using other email clients or apps that also access your contacts, it might cause conflicts. Try closing or uninstalling these apps to see if it resolves the issue.
  7. Check for software updates: Ensure that your macOS and Mail app are up to date. Go to System Preferences > Software Update and install any available updates.
  8. Try a different email account: If you have multiple email accounts set up in Mail, try switching to a different account to see if the issue persists.
  9. Reset your NDA (Name and Address) database: The NDA database stores your contacts and email addresses. Resetting it might resolve the issue. To do this, go to the Terminal app (located in Applications/Utilities) and type the following command: sqlite3 ~/Library/Group\ Containers/group.com.apple.mail/Database/ndatabase.sqlitedb "DELETE FROM contacts WHERE 1;" and press Enter.
  10. Reinstall Mail: If none of the above steps resolve the issue, you can try reinstalling the Mail app. Go to the App Store, search for Mail, and reinstall it.

If none of these steps resolve the issue, you may want to consider reaching out to Apple Support for further assistance.
