Hello, if you have access to another email account, try sending an email to this Yahoo account. If the email fails to send and is bounced back, then it would suggest that your Yahoo mail has been deleted.
There are a number of reasons why an email can be deleted. If this email account has been inactive for an extended period of time, this is one possibility.
Here is an article on how to recover your Yahoo account.
HI thanks I have tried all the steps but no luck.. I have sent an email to the account but it is also bounced back saying some system error. Does it means my account is being deleted but its my active account. is there any way to recover this because I use this account for my official and personal emails as well.
