how can i get my years old deleted emails from yahoo?

How can I get a Yahoo old account phone number that I had in  this account cause it had my iphone block cause it was years ago and I don't remember the phone number on that account

We can all retrieve our invaluable lost emails that yahoo has deleted by getting a job at NSA's Utah data storage facility cuz no data is "destroyed". All of our memorable lost emails are in fact out there but us peasants unfortunately do not have accsess to them anymore. I lost 20yr old emails

I saved old emails about settling an estate. Now when I open them the have an extension called "File"  What do I use to open them?

Congrats on asking your first question from a newly created YA account.  You should contact the people that sent these emails years old and ask them to forward another copy of the emails you wish to get.

You can't. You can't undelete anything that's been deleted past 7 days. It's like throwing something in your trashcan, then dumping all your household trashcans into the big garbage can outdoors, which is then emptied up by the trash removal company and taken to the landfill or recycle center. Once it goes to the 'dump' it's gone and you can't get it back. 

You can not, after 7 days deleted mail is gone and no longer exists.

Recover lost or deleted emails 

If any of your emails have been deleted or gone missing in the last 7 days, you can submit a restore request and we’ll do everything we can to try to recover your lost messages. 

Keep the following in mind: 

Restore requests can't be canceled. 

Restorations aren't always successful. 

Messages can only be restored if lost or deleted in the last 7 days, regardless of when they were originally received. 

Successfully recovered messages are added back to the same folder they were in during the time frame you pick to restore to. Check your Trash folder if you can't find them after the restoration is complete.
