You cannot truly delete a sent email from the recipient's inbox, but you can remove it from your own sent folder and stop it from reaching unopened recipients
Outlook has a feature called Recall that attempts to delete or replace a message you just sent, but it only works under specific conditions: the recipient must use Outlook or Exchange, the message must not have been opened yet, and both of you must be on the same corporate network or using the same Microsoft 365 organization. If any of those conditions fail, the recall fails silently — the recipient sees nothing, but your email stays in their inbox. For most people sending to Gmail, Yahoo, or other email services, recall does not work at all.
What you can always do is delete the email from your own sent folder, which removes it from your view but does not affect what the recipient has already received. You can also use the Undo Send feature if you catch the message within a few seconds of hitting send.
Key Takeaways
- Undo Send works only in the first 10 seconds after you hit send and gives you a window to stop the message before it leaves your computer.
- Recall only works if the recipient uses Outlook or Exchange, has not opened the message, and is on your organization's network or Microsoft 365 account.
- Deleting an email from your sent folder removes it from your view but does not delete it from the recipient's inbox.
- If recall fails, the recipient may see a notification that you tried to recall the message, which can draw attention to the email you wanted to unsend.
How to use Undo Send in the first 10 seconds
When you send an email in Outlook, a small notification bar appears at the top of the compose window with an Undo button. Click it when ready. This works because Outlook holds the message for a few seconds before actually transmitting it, giving you a brief window to change your mind.
The exact time window depends on your Outlook settings. By default, Outlook waits 5 seconds before sending, but you can extend this to up to 10 seconds. To change this setting in Outlook desktop: go to File > Options > Mail, then look for Send messages and check the box for Undo Send. A dropdown menu will let you choose how many seconds to delay. In Outlook on the web, click the settings gear icon, select View all Outlook settings, go to Mail > Compose and send, and toggle on Undo Send with your preferred delay.
How to attempt a recall in Outlook desktop
If more than 10 seconds have passed, you can try to recall the message, though success is rare. Open your sent folder, find the email you want to recall, and double-click it to open it. At the top of the message, click Message (or Home, depending on your Outlook version), then look for Actions and select Recall This Message.
A dialog box will appear asking whether you want to delete unread copies of the message or replace it with a new message. Choose one and click OK. Outlook will attempt to recall the message from each recipient's inbox. However, if the recipient has already opened the email, uses a non-Outlook email client, or is outside your organization, the recall will fail. You may receive a delivery report telling you whether the recall succeeded, but many recipients will see a notification that you tried to recall the message — which often makes them more curious to read it.
Why recall usually does not work
Recall relies on a feature built into Microsoft Exchange and Outlook that allows one Outlook client to command another Outlook client to delete a message. This only works when both people are using Outlook or Outlook on the web, both are connected to the same Exchange server (usually through a corporate network or Microsoft 365 account), and the recipient has not yet opened the message. If the recipient uses Gmail, Yahoo, Apple Mail, or any other email service, recall has no effect — the message is already in their inbox and cannot be remotely deleted.
Even within organizations where recall should work, it often fails because the recipient opened the message before the recall command arrived, or because their email client does not support the recall protocol. There is no way to know in advance whether a recall will work, and Outlook does not always tell you if it failed.
How to delete an email from your sent folder
If you want to remove an email from your own view, open your sent folder, right-click the message, and select Delete. The email moves to your deleted items folder. If you want to permanently remove it, go to deleted items, right-click it again, and select Delete or Permanently Delete. This removes the message from your account but does not affect what the recipient has already received.
In Outlook on the web, find the message in your sent folder, click the checkbox next to it, and click the trash icon at the top. The message goes to your deleted items. To permanently delete it, go to deleted items, select it again, and click the trash icon a second time.
What the recipient sees when you recall
If a recall attempt reaches the recipient before they open the message, Outlook may silently delete it from their inbox without any notification. However, if the recall fails or arrives after they have opened it, they may see a message saying something like "The sender has recalled this message" or "The sender would like to recall this message." This notification often appears as a separate message in their inbox, which can make them more likely to search for the original email or ask you what you were trying to hide.
For this reason, many people choose not to use recall at all, or they follow up with a direct message explaining the situation rather than relying on a silent deletion that may not work.
Alternatives if you cannot recall the message
If the recipient uses a non-Outlook email service or has already opened the message, your only real option is to send a follow-up email explaining the situation. You can ask them to disregard the previous message, provide corrected information, or explain why you sent it. This is often more effective than attempting a recall that will likely fail and may confuse them.
Some organizations have policies about email retention and deletion. If the email contains sensitive information and the recipient is within your organization, you can contact your IT department or email administrator to ask whether they can delete the message from the recipient's mailbox on the server side. This is not a standard feature and depends entirely on your organization's policies and technical capabilities.
Frequently Asked Questions
Can I recall an email I sent to Gmail or Yahoo?
No. Recall only works between Outlook and Exchange users on the same network or Microsoft 365 organization. Gmail, Yahoo, and other email services do not support the recall protocol, so the message stays in the recipient's inbox regardless of whether you attempt a recall.
What happens if I recall an email the recipient has already opened?
The recall will fail, and the recipient may see a notification that you tried to recall the message. The original email remains in their inbox. Outlook does not always notify you that the recall failed, so you may not know whether it worked.
Can I recall an email after more than a few minutes?
You can attempt to recall it at any time by opening the sent folder and using the Recall This Message option, but the longer you wait, the more likely the recipient has already opened it, which makes recall impossible. For practical purposes, you have only a few minutes before the window closes.
Does deleting an email from my sent folder delete it from the recipient's inbox?
No. Deleting from your sent folder only removes it from your view. The recipient still has the email in their inbox. To remove it from their inbox, you would need to use the Recall feature, which only works under specific conditions.
Is there a way to prevent someone from reading an email I sent?
Not reliably. Recall is the closest option, but it fails most of the time. Your best approach is to send a follow-up message as soon as you realize the mistake, or to contact the recipient directly by phone or message to ask them not to read or act on the previous email.
