You can't directly open a deactivated Yahoo email account. Once deactivated, the account and all its associated data are permanently deleted.
Here are some potential solutions:
- Contact Yahoo Support: You can try reaching out to Yahoo customer support. While they can't reactivate a deleted account, they might have information on recovering some data or alternative options.
- Create a New Account: If you need access to your old emails, consider creating a new Yahoo account. You can then use Yahoo's mail forwarding feature to redirect emails from your old address to your new one.
Remember, once you deactivate your Yahoo account, it's gone for good.
