How to Unsend an Email in Outlook is a question many people ask after sending a message by mistake. Maybe you clicked send too fast, or you sent the email to the wrong person. Don’t worry! Outlook has a feature that can help you take back your email, but you must act fast. This feature is called “Recall.” It lets you stop the email from being seen by the person you sent it to, but it only works in certain situations. In this blog post, we will explain everything you need to know in simple words so you can follow along without stress. We will go step-by-step and show you when and how you can unsend your email in Outlook. By the end of this post, you’ll feel more confident using Outlook and avoiding email mistakes.
Many people use Outlook at work or school, so learning how to unsend an email in Outlook is super helpful. But not all emails can be taken back. There are some rules. For example, it only works if the person you sent the email to is using Outlook too and is part of the same company or organization. Also, the email must not be opened yet. If they already opened it, you can’t take it back. That’s why it’s important to know how fast you must act. We will also talk about what to do if you can’t recall your email. Don’t feel bad if you make a mistake—it happens to everyone! This post will help you stay calm and fix things quickly. We will make sure every step is easy to understand, just like reading a story. Let’s learn how to use Outlook like a pro!
What Does “Unsend an Email in Outlook” Mean
When people talk about how to unsend an email in Outlook, they usually mean using the “Recall” feature. This tool allows you to take back an email that you sent by mistake. It only works if the receiver has not opened the email yet. Also, both you and the other person must be using Microsoft Outlook and working under the same organization or email server. So, if you sent an email too fast or typed the wrong message, recall can help you fix it—if you act fast.

When Can You Use the Recall Feature in Outlook
Outlook’s recall feature does not work for every email. There are some important rules to remember:
- Both you and the receiver must be using Outlook with Microsoft Exchange (same company or school email system)
- The receiver must not have opened the email yet
- The email must be sent from the desktop Outlook app (not web or mobile)
- The email must be in the receiver’s inbox (not moved to another folder)
If all these things are true, then you can try to unsend the email. But remember, if the other person opens the message first, it’s too late to recall it.
How to Unsend an Email in Outlook (Step-by-Step)
Here’s how to unsend an email in Outlook using the Recall tool. Follow these easy steps:
- Open your Outlook desktop app.
- Go to the “Sent Items” folder on the left side.
- Click on the email you want to unsend.
- In the top menu, click “Message” tab.
- Choose “Actions” then click “Recall This Message…”.
- A pop-up will appear. You will see two choices:
- Delete unread copies of this message
- Delete unread copies and replace with a new message
- Delete unread copies of this message
- Choose the one you want, then click OK.
That’s it! If it works, the email will disappear from the other person’s inbox. You can also get a message from Outlook telling you if the recall worked or failed.
What Happens After You Try to Unsend
After you try to unsend your email in Outlook, a few different things can happen:
- If the person has not opened the email, the message will be removed.
- If the person already opened it, Outlook will tell you that the recall failed.
- If you chose to replace the email, the new message will be sent after the old one is removed.
Outlook may also send you a status update in your inbox. It will say if your recall worked or failed. Keep an eye on it to know what happened.
How to Replace a Recalled Message
Sometimes, you not only want to remove the email but also send a corrected version. Outlook lets you do that.
- After clicking “Recall This Message…”, choose the second option:
“Delete unread copies and replace with a new message.” - Click OK.
- A new message window will open with the same content as the old one.
- Edit your message, fix any mistakes, and click Send.
This will send the new email, and Outlook will try to replace the old one if it hasn’t been read yet.

Why Email Recall Might Not Work
Even if you follow the right steps, recall doesn’t always work. Here’s why:
- Email already opened: The person saw your message before the recall could happen.
- Different email system: If the receiver is using Gmail, Yahoo, or another non-Outlook account, the recall will fail.
- Not using Exchange server: The recall feature only works with Microsoft Exchange servers.
- Rules or filters: The receiver might have rules that move emails out of the inbox, which can stop recall from working.
- Using web or mobile version of Outlook: You must use the desktop version to unsend.
Always check these things before trying to recall a message. If the recall fails, don’t panic—there are still ways to handle the situation.
What to Do If You Can’t Unsend the Email
Sometimes, you won’t be able to unsend an email in Outlook, and that’s okay. Here are a few things you can do instead:
- Send a follow-up email: Say sorry and explain the mistake in a polite message.
- Call or message the person: Let them know not to read the email or that it was a mistake.
- Be honest: People make mistakes. Most people will understand.
- Set a delay on future emails: This gives you extra time to cancel emails before they’re sent (more on this below).
Learning from the mistake is the best thing you can do.
How to Delay Emails in Outlook to Prevent Mistakes
Want to stop email mistakes before they happen? You can set Outlook to delay sending your messages. This gives you time to change your mind.
Here’s how to do it:
- Open Outlook.
- Click File > Manage Rules & Alerts.
- Click New Rule.
- Under Start from a blank rule, choose Apply rule on messages I send.
- Click Next, then click Next again (say Yes to the warning).
- Choose “defer delivery by a number of minutes” and set your time (like 2 minutes).
- Click Finish.
Now your emails will wait a few minutes before sending. You can open your outbox and delete or fix them before they go.
Outlook Web and Mobile: Can You Unsend from There
Right now, the recall feature doesn’t work on Outlook Web or the mobile app. These versions don’t have the same tools as the desktop app. But there’s still a helpful trick!
If you’re using the Outlook Web App, you can turn on Undo Send:
- Click the Settings gear icon (top right).
- Search for Undo Send.
- Set the time (up to 10 seconds).
- Click Save.
After you click Send, you’ll see a small “Undo” button for a few seconds. Click it fast to stop the email.
This won’t help with big mistakes, but it’s great for quick fixes like typo errors or wrong attachments.
Best Practices to Avoid Email Mistakes
Even if you know how to unsend an email in Outlook, it’s better to avoid mistakes in the first place. Here are some simple tips:
- Always double-check the To, Subject, and Body before clicking Send.
- If it’s an important email, ask someone to review it.
- Don’t write emails when you’re too tired or angry.
- Use Delay Send to give yourself extra time.
- Add attachments before writing the email so you don’t forget.
- Save drafts if you’re not sure, and come back later.
By taking a little extra time, you can stop mistakes before they happen.
How to Check If Your Email Recall Worked
Want to know if your email was successfully unsent? Outlook can tell you.
After you try to recall the message, you will get a status update. Look in your inbox for a message titled “Message Recall Report.”
This message will tell you:
- If the recall worked or failed
- Who it worked for
- Who it failed for
If it says Recall Failed, that means the person probably opened the email already or the settings didn’t match. If it says Recall Succeeded, then your message was removed.
Reading this report helps you stay informed and take the next step.

Conclusion
Learning how to unsend an email in Outlook is very helpful, especially if you send emails at work or school. Outlook gives you tools like “Recall This Message” and “Delay Send” to fix or prevent email mistakes. But it’s important to remember that the recall feature only works in some cases, like when both people use Outlook on the same system and the email hasn’t been opened. Even if the recall doesn’t work, you can still fix the problem with a follow-up message or by being honest. Email mistakes happen to everyone, and now you know what to do when they do. Use the tips in this post to become more careful and confident with your emails in Outlook.
