Sent an email you wish you could take back? It happens more often than you think.
Outlook gives you a few ways to unsend an email or recall it, but the steps depend on which version you are using.
Classic Outlook desktop has a full recall feature, while the web and mobile apps use a timed undo delay instead.
Each method has different limits, and knowing which one applies to your setup saves you time.
Below, you will find step-by-step instructions for every version of Outlook, so you can get the answer to your question: how to rescind an email in Outlook? And act fast the next time a sent email needs to disappear.
Which Version of Outlook Are You Using?
The first thing to figure out is which Outlook version you have, because each one handles sent emails differently.
Classic Outlook for desktop includes a full recall feature that can remove an unread message from the recipient’s inbox.
New Outlook for Windows and Outlook on the web both use an “Undo Send” delay that holds the email for a few seconds before it goes out.
The mobile app also offers a short undo window right after you tap send. Once you know your version, you can jump straight to the right set of steps.
How to Recall an Email in Outlook in Each Version
The buttons sit in different places across new Outlook, classic Outlook, the web version, Mac, and mobile. Open the message itself rather than leaving it in the reading pane.
New Outlook for Windows

New Outlook gives eligible Microsoft 365 users a direct ribbon command to request removal and review results for every recipient.
Open the left folder pane and select Sent Items to view messages that have already left your Microsoft 365 mailbox.
Find the message you need to remove, then double-click it to open it in a separate window for editing.
Look across the open message ribbon and select Recall Message to request removal from the mailboxes of all eligible recipients.
Read the confirmation box, verify the intended message, and select OK to submit your recall request for Microsoft 365 processing.
Wait for the Message Recall Report to arrive in your inbox, then open it rather than assuming the removal succeeded automatically.
Review every listed recipient and check the individual status to see which mailbox copies were removed, are pending, or were unsuccessful overall.
Classic Outlook for Windows

Classic Outlook offers removal and replacement choices through its message menus, including an option to receive per-recipient status updates afterward.
Open Sent Items from the folder pane, locate the affected message, and double-click it to launch a separate message window.
Open the Message tab, select Actions, and choose Recall This Message from the menu displayed beneath the Outlook ribbon controls.
When using the simplified ribbon, select the three-dot button, point to Actions, and choose Recall This Message from its menu.
If that command remains hidden, open File, choose Info, select Resend or Recall, and then choose Recall This Message instead.
Choose Delete unread copies to remove it, or select the replacement option when you need to correct and resend the message.
Request success or failure updates for each recipient, review your selection, and select OK to send the recall request immediately.
Outlook on The Web

Outlook on the web supports recall for eligible Microsoft 365 work or school accounts, while personal Outlook.com mail remains excluded.
Sign in with the correct work or school account, open the left folder list, and select Sent Items.
Locate the sent message and double-click it to display the full message its a separate browser window.
Open the ribbon above the message, then select Recall Message to start removing copies from recipients’ mailboxes within the organization.
Read the confirmation dialog carefully, then select OK to submit the request for processing by your organization’s Microsoft 365 service.
Open the Message Recall Report after delivery and review every recipient status before treating the original message as successfully removed.
Outlook for Mac

Outlook for Mac version 16.94 or later lets eligible company and school accounts request removal through the open message ribbon.
Select Sent in the folder pane, find the message, and double-click it to open it in a separate message window.
Find Recall Message on the ribbon above the open message, select it, and wait for Outlook to show confirmation options.
Review the message details shown in the confirmation box, then select OK to submit your removal request to Microsoft 365.
Watch your inbox for the status report, open it, and review the recorded result for every person who received it.
You may also Control-click the sent message, open its shortcut menu, and select Recall when the ribbon button is unavailable.
Outlook for Android or iPhone

Mobile recall may appear for supported Microsoft 365 accounts, though the command can change with app releases and company settings.
Open the Outlook app, select the work or school account, enter Sent, and open the message you need to remove.
Open the message options and look for Recall Message, which appears only when your account and organization support mobile recall.
If Recall Message is missing, update Outlook through your app store and reopen the message from the same mailbox afterward.
Try the same mailbox through desktop Outlook or Outlook on the web when the mobile command remains unavailable after updating.
Wait for the recall report and read each recipient’s result before assuming the message was successfully delivered to every eligible mailbox.
When Does Recalling an Email Actually Work?
Outlook recall works only when the sender and recipient use eligible Microsoft 365 work or school accounts within the same organization.
The message must also remain eligible for removal when the recall request is processed. Messages sent to external accounts, including Gmail or other organizations, generally cannot be recalled.
Recall success can vary by account setup and organization policies, so sending a request does not guarantee removal.
Check the Message Recall Report afterward to confirm whether Outlook successfully recalled the email for each recipient.
How Long Do You Have to Recall an Email in Outlook?
There is no official time limit on the Recall This Message feature itself. Technically, the recall request can work as long as the original message sits unread in the recipient’s inbox.
But in practice, every minute that passes increases the chance that the recipient opens the email or that a mail rule moves it. For the Undo Send delay on the web, New Outlook, and mobile, the window is fixed at whatever you set it to.
Options vary by version and typically range from 5 to 30 seconds. Check your Outlook settings under Mail > Compose and reply > Undo send to see the available choices. After that, the email is fully sent.
If more than a few minutes have gone by and you are not confident the recall will succeed, sending a polite follow-up correction is usually a safer bet than waiting and hoping.
Can You Pull Back an Email Sent Outside Your Organization?
Recall only works within the same Exchange or Microsoft 365 organization. For external recipients, Undo Send is your only pre-send option. If the email already went through:
- Send a follow-up email asking the recipient to disregard the original.
- Call or message them directly if the situation is time-sensitive.
- If the email contained sensitive information, notify your IT department for next steps.
- Set up Undo Send as a safety net for all future external emails.
- Ask the recipient to delete the original without opening it if they have not read it yet.
- Review your Sent folder to confirm exactly what was included before deciding on your next step.
How to Know If Your Recall Worked
If you checked the “Tell me if recall succeeds or fails” box during the recall process, Outlook sends you a notification email for each recipient.
These arrive in your regular inbox. A successful recall notification confirms the original message was removed.
A failed notification means the recipient still has the original, and you may want to follow up with a correction.
Keep in mind that if the recipient is using cached or offline mode, the recall result might take longer to appear.
You may not get the notification right away.
Tips to Stop Needing The Undo Button
Catching mistakes before they happen beats scrambling to recall them after. A few small changes to your Outlook setup can save you a lot of stress.
- Turn on Undo Send across every version of Outlook you use, and set it to the maximum delay.
- Set up a “Delay Delivery” rule to hold all outgoing mail for 1 or 2 minutes. Go to Rules, create a new rule, and choose “defer delivery by X minutes.” This gives you a buffer on every email.
- Double-check the “To” and “CC” fields before you start typing the body. Wrong-recipient mistakes are the hardest to fix after the fact.
- Use “Schedule Send” for anything sensitive or high-stakes. This lets you review the email one more time before it goes out at the scheduled time.
- Read the full email out loud before sending. You will catch phrasing issues and missing context that you would skip when reading silently.
Wrapping Up
Now you know exactly how to unsend an email in Outlook, whether you use the classic desktop app, the web version, New Outlook, or your phone.
The recall feature works well when both sides are on the same Exchange server, and the email has not been opened yet.
For everything else, the Undo Send delay is your fastest safety net, so turn it on now if you have not already.
Set it to 20 seconds on every device you use. Small habits like send delays and delivery rules prevent most of these panic moments before they start.
