What if my account is terminated? You’ll lose access to all of your data and content, such as emails, email folders, calendars, Yahoo Fantasy teams, and Yahoo Finance portfolios.
It takes around 90 days for Yahoo! to complete the removal process. If you want your data removed from Yahoo’s servers sooner, go through it and delete it yourself.
Deletion of a Gmail account is irreversible. All of your emails and account settings will be deleted after you complete the procedure. You will no longer be able to use your Gmail address to send or receive emails, and it will not be made available for anybody else to use in the future.
Sign in to Yahoo Mail and go to the preferences menu. Look in your Trash or spam/junk email folder for the correspondence. All you have to do now is move it back to its original location if you can discover it in the trash or junk email folder. “Request a Repair” from the drop-down menu
As a result of this, your deleted emails will not be kept indefinitely. After a pre-determined period of time, Yahoo deletes your Trash and Spam folders automatically — trash emails remain in the Trash for seven days, while spam emails are kept in the Spam folder for 30 days – and these settings cannot be changed.
