How to Unsend an Email in Outlook?

Sending an email only to realize moments later that you made a critical mistake or sent it to the wrong recipient can induce a wave of panic.

However, if you’re an Outlook user, you’re in luck! Outlook offers a valuable feature that allows you to unsend emails, saving you from potential embarrassment or unintended consequences.

In this article, we’ll guide you through the process of unsending an email in Outlook, ensuring that you can swiftly rectify any mistakes before they become permanent.

Steps to Unsend an Email in Outlook

Step 1: Enable the “Undo Send” Feature:

By default, Outlook grants users a short window of opportunity to recall sent messages. To ensure you have this capability, follow these steps to enable the “Undo Send” feature:

  • Launch Outlook on your computer and go to the File tab located at the top left corner of the screen.
  • In the File tab, select “Options” from the sidebar menu.
  • In the Outlook Options window, choose “Mail” from the left-hand menu.
  • Scroll down until you find the “Send messages” section.
  • Check the box next to “Undo Send” and adjust the time delay to your preference. The default time frame is 10 seconds, but you can extend it up to 30 seconds.
  • Click “OK” to save the changes and exit the Options window.

Step 2: Sending an Email:

Now that you have enabled the “Undo Send” feature, you can proceed to send emails as usual. Compose your email, add recipients, and include any necessary attachments. Double-check the content and recipients before hitting the “Send” button.

Step 3: Unsend the Email:

If you realize you’ve made an error or have second thoughts about sending an email, the following steps will allow you to unsend it:

  • After sending the email, look for the “Message Sent” notification at the bottom-right corner of the Outlook window.
  • Immediately after the message is sent, a yellow box will appear with the option to “Undo” the send. Click on the “Undo” button within the specified timeframe (e.g., 10 or 30 seconds).
  • The email will be recalled and returned to your Drafts folder, allowing you to make the necessary modifications or reconsider sending it altogether.

Note: If the “Undo” option disappears before you can click on it or if you close Outlook, the recall feature will no longer be available, and the email will be sent as intended.

Step 4: Modifying the Email:

Once the email is back in your Drafts folder, you can open it, make the necessary changes, and review it before attempting to send it again. Take this opportunity to correct any mistakes, adjust the recipients, or revise the content according to your needs.

Step 5: Resending the Email:

After you have modified the email, you can resend it by following these steps:

  • Open the email in your Drafts folder.
  • Review the changes and ensure everything is correct.
  • Click the “Send” button to resend the email to the intended recipients.


Thanks to the “Undo Send” feature in Outlook, the dread of mistakenly sending an email with errors or to the wrong recipient can be quickly alleviated.

By following the simple steps outlined in this guide, you can regain control over your sent messages, allowing you to rectify any issues or second thoughts before they become permanent.

Remember to enable the “Undo Send” feature in your Outlook settings to make the most of this valuable feature and enhance your email experience.
