Sending an email to the wrong person--or a wrong email to the right person--can be embarrassing, costly and detrimental. Usually, once you hit send, there isn't anything you can do about it. However, if you are using Outlook Express, AOL, or certain private email companies, there might be something you can do. These processes only work if the receiver uses the same type of email service as you do, and the email has not yet been read.
Click on your "Sent" message folder.
Find the message you would like to recall. If it was sent to someone using the same email service as you do and the message has not been read, and if your email client allows you to, choose the option "recall message."
Click "Yes" to recall the message and then click "Delete all unread copies of this message" to make sure it is recalled and deleted.
