OR: Just create the new account. Delete your old profile and any other information you don't want on there. Then just abandon that I.D.

I need more information. Did you not use the account for a long time? Most free email providers will erase disable accounts that have not been logged into in x amount of time in preparation to recycle the address. When this happens they usually will delete the contents of the mailbox to free up space on their servers, assuming you don't want the content because you have not logged in to show interest. Depending on the lenth of time that the account has not been accessed you can recover the account (the address) sometimes, the provider usually will explains the time stipulations and grant you permission to continue using that address, but without any of the content, so for all intendided purposes this is actually a new account with an old name. Kinda like number porting. Is this your situation? More questions? Just ask

HOW LONG HAS IT BEEN INACTIVE ?

Your Yahoo ID is linked to a broad array of Yahoo services, from Yahoo Messenger to online games. A Yahoo ID must be deleted from a laptop or desktop, not a mobile device. Only get rid of your Yahoo ID if you're certain you'll never need it again, because there is no option to change your mind and get your ID back once it's gone.

Deleting a Yahoo ID
When you delete a Yahoo ID, you lose access to all programs associated with it, including Yahoo Mail, Yahoo Groups and Yahoo Finance Portfolio. Deleting your Yahoo ID will not remove your listing from the Yahoo People Search, however, so your profile will continue to appear in search results unless you delete your listing before deleting your ID. Lost Information b> When a Yahoo ID is removed from the system, Yahoo deletes all of the data associated with the account, including your email messages. You cannot recover this information once it is removed; creating a backup copy of your data on a computer or external storage device is the only way to preserve it for future reference. b> Reactivating Dormant Email As long has your Yahoo email has only gone dormant -- and not been deleted as the result of an ID termination -- you can reactivate the account. Yahoo automatically makes an email account dormant if the user hasn't signed in more than four consecutive months. To reactivate such an email account, you must sign in via computer using your Yahoo ID and password, and choose "Reactivate Without Account Protection." Yahoo permanently deletes old emails when an account is deactivated, but you can resume sending and receiving email once you reactivate the account. b> Considerations b> Some premium services are not cancelled along with a Yahoo ID deletion. If you signed up for a paid service, such as Yahoo Mail Plus, the company recommends manually canceling the service -- independent of your Yahoo ID deletion -- to avoid future bills. Canceling a Yahoo ID doesn't disqualify you from signing up again in the future with a new ID, but you cannot reactivate the same ID. Hope this helps.

How do you access your Yahoo mail? Is it via the browser (www.yahoo.com) or via MS Outlook?

If you're having a problem of sending/receiving emails while using the web browser, you may want to delete old and unnecessary emails. You could have reached the storage limit of your email account.

But if your using an Outlook, you need to double-check the account settings. Make sure that you have the correct user name, password, incoming and outgoing servers, incoming and outgoing ports.

If you setup your email account using the POP protocol, you may use these server ports:

Incoming: 110 or 995
Outgoing: 25 or 2525, or 587, or 465 (SSL)

For IMAP:

Incoming: 143 or 993
Outgoing: 25 or 2525, or 587, or 465 (SSL)

If the same problem occur, you may try to delete your account and recreate it. Please bear in mind that if you deleted your account and recreated it, some emails may no longer appear or get downloaded.

Thank you and good luck!

You cant delete an email account unless you have access to it.Only way to delete an account is to log in to the account and there you will find a delete option.
