How do you reactivate a ymail account that may have been deactivated due to inactivity?

To reactivate a Ymail account that may have been deactivated due to inactivity, visit the Yahoo sign-in page and enter your Ymail address and passWord. If the account is still recoverable, you should be prompted to reactivate it. If you can't access it, try using the account recovery options provided by Yahoo, such as answering security questions or using a recovery email or phone number. Keep in mind that accounts deactivated for an extended period may not be recoverable.
