It is possible to cancel an e-mail that has already been sent, but under certain conditions. You must use Gmail or MS Outlook2007 / 2010 and have an MS Exchange Server 2000/2003/2007 account. In other cases, the already completed sending of the e-mail cannot be canceled.
Instructions
Step 1
Most email services do not use Exchange, but if you still have this type of account and use MS Outlook 2007/2010 to send emails, follow these steps.
Step 2
Select the Sent Items folder under Mail in the Navigation Pane. Next, open the letter you want. In the Actions group of the Messages tab, choose More Actions. Next, select "Revoke the message" and check "Delete unread copies".
Step 3
Then indicate whether the email should be replaced with a new one or just needs to be deleted. Confirm your choice.
Step 4
In addition to the attempted revocation of the letter, you can send a new letter instead of the previous one. For example, if you accidentally forgot to attach an attachment, this feature will be very useful to you. You will be able to replace the old letter with a new one with the desired attachment.
Step 5
In this case, the procedure remains the same, only after selecting the item "Message revocation" you will need to specify a different value, namely "Delete unread copies and replace them with new messages."
Step 6
Then click on the "OK" button to save the changes. Also you can add or remove any attachment / attachments. For the changes made to take effect, click on the "Submit" button.
Step 7
If you use Gmail to send emails, go to your inbox using any browser you like. Go to the section called "Settings", then open the "Lab" tab. Agree to the experimental feature request from Gmail.
Step 8
Activate the functions "Cancel sending a letter", and then save the changes. Now, if you accidentally send a letter, you will have the opportunity to recall it within a few seconds after sending it.
