Autocomplete is not working
Autocomplete in Yahoo Mail (the feature that auto-fills email addresses as you begin to type them) may not work due to issues with your browser, contacts, or Yahoo Toolbar.
Why Autocomplete may not work
- Make sure you're using a browser supported by Yahoo Mail.
- You're sending a message to someone who's not in your contacts or that you haven't sent messages to in the past.
- You don't have the latest version of Yahoo Toolbar.
- Go to Yahoo Toolbar to get the latest version.
