If your mail account has been deactivated, you'll see a message when you log in. It might say your account's been deactivated or that you're unable to reset your password. Information in this article applies to the web versions of Yahoo Mail as well as the Yahoo Mail mobile app for iOS and Android. After your account is deleted, your screen name becomes available to new users. If someone claims it, you'll need a different screen name for your new account. Yahoo Mail periodically deactivates unused accounts. If your account is deactivated, you won't have access to emails, attachments, and the other elements of your account. Why Yahoo Mail Deactivates Accounts If you go more than a year without logging into your Yahoo Mail account, Yahoo may delete your messages from its servers to make room for other users. Inactive accounts slow down the service for everyone, so keeping things tidy on Yahoo!'s end allows their mail service to be fast and reliable for those who use it. Aside from inactivity, Yahoo might close your account if you request Yahoo to delete your account or you violate the Yahoo terms of service. How to Keep Your Yahoo Account Active To make sure your Yahoo Mail account stays active, simply log in every now and then. If you use multiple email providers, sync your other email accounts with Yahoo Mail so that you get all your messages in one place. That way, you can read your emails in Yahoo Mail, and you'll prevent your account from getting deleted.
