How to Unsend on Outlook

Need to pull back an email right after sending it in Outlook? The recall feature lets you unsend messages when both you and the recipient use the same Microsoft Exchange or Microsoft 365 server. This article explains exactly how to unsend on Outlook with clear steps that work in the desktop app.

How to Unsend on Outlook: Requirements First

Before attempting to recall any message, confirm you meet the technical conditions. The feature only works inside an Exchange or Microsoft 365 environment. It fails if the recipient has already read the email or if either mailbox sits on a different mail system such as Gmail or a POP account. Open Outlook and check your account type in File > Info > Account Settings to verify you are connected to the correct server.

Step-by-Step Guide to Unsend on Outlook

1. Open the Sent Items folder

   Launch the Outlook desktop application on Windows. In the left navigation pane click Sent Items. Locate the message you want to retract and double-click it so it opens in its own window instead of the reading pane.

   

2. Access the Recall command

   With the message window active, click the Message tab on the ribbon. In the Move group select Actions, then choose Recall This Message from the dropdown list. If you do not see the option, the account does not support recall.

3. Choose recall options

   In the dialog box that appears, select Delete unread copies of this message. Optionally check the box labeled Tell me if recall succeeds or fails for each recipient. Click OK to send the recall request.

   

4. Verify the result

   Outlook sends a recall notification to recipients. Check your Inbox for any success or failure reports if you selected that option. The original message remains in your Sent Items folder even after a successful recall.

Common Issues When Trying to Unsend on Outlook

• The recall button is missing when the account uses IMAP or POP3 instead of Exchange. Switch to a supported account or ask the recipient to delete the message manually.
• Recipients using Outlook on the web or mobile apps often receive the recall message as a new email rather than an automatic deletion. In these cases the original message stays visible.
• If the email has already been read, the recall attempt fails. Act quickly after sending to improve success rates.
• Attachments and voting buttons are not removed by recall. Consider sending a follow-up message with corrected content when recall is not possible.

Frequently Asked Questions

Can I unsend on Outlook Web or the new Outlook app?

No. The recall feature exists only in the classic Outlook desktop application for Windows. Outlook on the web offers an Undo Send delay instead, adjustable up to 10 seconds under Settings > Mail > Compose and reply.

Does recall work across different organizations?

Only when both organizations use the same Exchange or Microsoft 365 tenant with proper cross-forest trust. Most external recipients will simply receive your recall request as a normal email.

What happens if recall fails?

The original message stays in the recipient mailbox. You receive a failure report if you requested one, and you can then send a corrected follow-up email explaining the situation.

Conclusion

Mastering how to unsend on Outlook prevents small mistakes from becoming larger problems when the technical requirements are met. Use the steps above the next time you need to retract a sent message.
