When an account is deactivated, you won't be able to access it, regardless of whether or not email has been received in the account during that time.

And sorry, but you can't retrieve any of the information that was formerly stored in it.

You will lose access to your Yahoo! ID, Yahoo! Mail, and profile names. yahoo will also delete your account data and settings across the Yahoo! network. This includes any contents in:

Yahoo! Mail

Yahoo! Address Book

Flickr

Yahoo! HotJobs

GeoCities

Yahoo! Briefcase

My Yahoo!

Yahoo! Groups

Finance Portfolio

( Or any other area of Yahoo! that can only be accessed with your Yahoo! ID and password )

This Is From The Account Deletion Page

In most cases your account will be deactivated and then deleted from our user registration database in approximately 90 days.

This delay is necessary to discourage users from engaging in fraudulent activity. Additionally, due to the limited number of names available,

we (MAY)allow other users to sign up for and use your current Yahoo! ID and profile names after your account has been deleted.

it is (NOT) automatic that you can get or anyone can get that user id again

Create A New Yahoo Email Account

(if you want an id close to the old one you

can add numbers or letters to the old id)

Sign Up
