If your account was deactivated more than 90 days ago it has been permanently deleted and removed from the system. All your information stored inside that account has also been permanently deleted.

Yahoo Mail accounts are deactivated and removed after twelve months of inactivity. Accounts are deemed "inactive" when they are not logged into for a long time regardless of whether or not the account is still receiving email. Signing in via an email client, such as Microsoft Outlook, Mac Mail, or a mobile phone mail application is not considered a valid login. You must sign in to your account on a Yahoo! web site using an Internet browser (Internet Explorer, Safari, Firefox, Chrome).

You will know that a Yahoo! account has been deleted if you cannot sign in to any of Yahoo!'s services using that Yahoo! ID or any aliases associated with it.

Once an account has been deactivated, it's impossible for the Yahoo! Mail team to retrieve any stored information.

In the future, please consider saving all your important information, messages and contact information to your personal computer files using an application such as Wordpad, Microsoft Word, Oracle Open Office Writer etc.

Messages, emails and even your contact list can be printed and the physical copy kept in a safe place.

Email accounts are intended to be used as a form of communication and not as storage units. Accounts are at risk for hackers, deletion, or you could be denied access to your account due to a forgotten password or forgotten answers to you secret questions. Content stored in your mail account is always vulnerable. Please consider this in the future.
