You have sent an email with a mistake or to the wrong person and want to take it back. The recall feature in Outlook attempts to delete or replace an unread message from a recipient’s inbox. This article explains the strict conditions required for a recall to succeed and provides the exact steps to attempt it.
Key Takeaways: Recalling an Outlook Message
- Message > Actions > Recall This Message: Opens the recall dialog to delete or replace a sent email from recipient inboxes.
- Delete unread copies / Delete unread copies and replace: The two recall options, which only work if the recipient uses Outlook on the same Microsoft Exchange server.
- Tell me if recall succeeds or fails for each recipient: A critical option to select for receiving a report on the recall attempt’s outcome.
How the Outlook Recall Feature Operates
The recall function is not a universal undo for email. It is a specific command sent to a Microsoft Exchange Server, which then tries to act on the original message stored in recipients’ mailboxes. For this to work, both you and all recipients must be on the same Exchange organization, such as the same company’s email system.
The recall process does not reach into external email services like Gmail or Yahoo Mail. It also fails if the recipient uses a different email client to access their Exchange mailbox, such as Outlook on the web or a mobile app. The command only interacts with the mailbox when accessed via a compatible Outlook desktop client.
Prerequisites for a Successful Recall
Several technical conditions must all be true for a recall to work. The original message must still be unread and remain in the recipient’s Inbox folder. If the recipient has any rule that moved the message, opened it, or previewed it in the Reading Pane, the recall will fail. Both users must also have an active connection to the Exchange server during the attempt.
Steps to Attempt an Email Recall
Follow these steps precisely from the Outlook desktop application connected to a Microsoft Exchange account.
- Open your Sent Items folder
Navigate to the folder containing the message you wish to recall. Double-click the sent email to open it in a separate window. You cannot initiate recall from the reading pane. - Select the recall command
With the message window open, go to the Message tab on the ribbon. In the Move group, click Actions, and then select Recall This Message from the dropdown menu. - Choose your recall action
In the Recall This Message dialog box, you will see two primary options. Select Delete unread copies of this message to simply remove it. Choose Delete unread copies and replace with a new message if you need to send a corrected version. - Configure notification settings
Below the main options, check the box for Tell me if recall succeeds or fails for each recipient. This is essential to receive a report in your Inbox detailing the outcome for every person you sent the original email to. - Complete the process
Click OK. If you selected the replace option, a new message window will open for you to compose the replacement. Send it to complete the recall attempt.
Common Reasons a Recall Attempt Fails
The recipient is not on the same Exchange server
This is the most common failure point. The recall feature is exclusive to Microsoft Exchange. If you sent the email to a Gmail, Yahoo, or other external address, the recall command cannot be delivered or acted upon. It will always fail.
The recipient has already read the message
Recall only works on unread messages. If the recipient opened the email or even previewed it in the reading pane, which marks it as read, the recall attempt will not delete the message from their inbox. The system considers the transaction complete.
The recipient uses Outlook on the web or a mobile app
Even within the same Exchange organization, the recall command is designed for the classic Outlook for Windows client. If the recipient accesses their mailbox through Outlook on the web in a browser or the Outlook mobile app, the recall mechanism often does not trigger, leaving the original message in place.
Recall Success Scenarios vs Failure Scenarios
| Item | Scenario Where Recall Works | Scenario Where Recall Fails |
|---|---|---|
| Recipient Mail System | Same Microsoft Exchange organization | External email like Gmail, or a different Exchange forest |
| Message Status | Message is unread and in the Inbox | Message has been read, moved, or deleted |
| Recipient Client | Outlook for Windows or Mac desktop app | Outlook on the web, mobile app, or other email client |
| Timing | Attempted quickly before the recipient acts | Attempted after a delay, allowing the recipient to see it |
| Replacement Message | Can be sent if the original is deleted successfully | May send a new, separate email if recall fails |
You now know how to initiate an email recall and understand its significant limitations. Always select the option to receive success or failure reports to track the attempt. For more reliable control, use the Delay Delivery rule in Outlook to give yourself a brief window to stop a message before it leaves your outbox. A practical advanced tip is to recall a message sent to a colleague’s test mailbox first to verify your organization’s recall behavior before trying it on a critical email.
