Understanding the Recall Function in Outlook
What is Email Recall?
Email recall is a powerful feature designed to help you take back messages you’ve already sent. When you initiate a recall, Outlook attempts to intercept your email before the recipient opens it. It either deletes the message from their inbox or replaces it with a corrected version. This cloud-based system relies on the Message Recall feature agent to intercept and remove the original email from recipient mailboxes.
It’s a lifesaver when you’ve sent an unfinished, mistaken, or embarrassing email and need to undo that action immediately. However, it’s essential to understand that email recall is not perfect and comes with specific conditions you must meet.
How to Recall an Email in Outlook
The process for recalling an email in Outlook depends on the version of the desktop application you’re using. If you’re using the classic Outlook for Windows, start by navigating to your Sent Items folder. Locate the email you want to recall and double-click it to open it in a separate window.
Once the message is open, click on the Actions icon located in the Move group on the ribbon, then select Recall This Message. A dialog box will appear with options—you can choose to delete the message from the recipient’s inbox or replace it with a corrected version.
If you choose to replace the message, make your edits and hit send. You’ll then receive a message recall report indicating whether the recall succeeded or failed for each recipient.
For those using newer versions of Outlook, the steps are slightly different. Go to File > Info, then select Resend or Recall from the dropdown menu.
Choose Recall This Message… to proceed with the recall process. Ensure you check the box that says “Tell me if recall succeeds or fails for each recipient” so you have a clear understanding of whether your action was successful.
When you click OK, Outlook will attempt to delete unread copies of your email from recipient inboxes.
Limitations and Considerations
Before attempting to recall a message, it’s important to understand the feature’s limitations. The most significant restriction is that recall won’t work if you’re sending emails outside your organization. If the recipient uses a different email provider or works at another company, the recall function will fail because it only works when both sender and recipient are on Microsoft Exchange or Microsoft 365 within the same organization.
Additionally, if your account is a MAPI or POP account, the recall functionality will not be available to you.
Another key consideration is that the success rate is not guaranteed. The outcome depends on several factors, including whether the recipient has already read the message and the settings configured by your IT administrator. While newer versions of cloud-based recall can now work on read messages (if enabled by your admin), the classic version traditionally only recalls unread messages.
Your organization’s IT administrator can set a recall time limit ranging from 5 minutes to 10 years, which may significantly narrow the window for successful recall attempts. Additionally, when a recall is initiated, the recipient is notified of the action, which can spark curiosity about the content you were trying to retract.
Keep in mind that message recall has only about a 50% success rate in practice. It should not be your sole safety net when sending critical emails.

Configuring “Undo Send”
The Undo Send feature in Outlook serves as a safeguard by delaying the actual sending of your email. This gives you a few seconds to change your mind before the email reaches the recipient. Note that this feature must be manually enabled and is primarily available in the New Outlook versions, Outlook on the web, and Outlook for Mac with a Microsoft 365 account.
To configure this feature, open the Outlook Settings menu by clicking the gear icon, then navigate to Compose and reply. Scroll down to the Undo send section, where you can set a delay time ranging from 0 up to 10 seconds (or even longer on Mac).
Adjust the slider to your preferred delay time, then click Save to activate this buffer period. This allows you to cancel sending if you notice an error immediately after hitting send.
How to Use “Undo Send”
Once configured, using Undo Send is simple. After composing your email and clicking send, you’ll see a notification at the bottom of your Outlook window indicating that your message is still sending.
During the delay time you set, you have the option to click an Undo button. This pauses the send operation and returns the email to edit mode. You can then make necessary corrections, add attachments you may have forgotten, or even decide not to send the email at all.
After the delay period expires, the message is delivered and can no longer be undone using this feature. This method is particularly effective for catching last-second mistakes before they become permanent in the recipient’s inbox.
Tips for Effective Use
To maximize the benefits of the Undo Send feature, consider these tips:
First, set the delay time to the maximum you’re comfortable with (up to 10 seconds is common) to ensure you have enough reaction time. Second, develop a habit of reviewing your email carefully, but also be prepared to hit Undo quickly if you notice an issue after clicking send.
Third, avoid relying solely on this feature to fix all your mistakes—it’s a helpful last-minute safety net but not a replacement for thorough proofreading and recipient selection. Lastly, remember that Undo Send only delays messages. If you need to retract an email after it has been sent and potentially opened by the recipient, you’ll need to use the traditional recall message feature, which has its own limitations.
Best Practices When Retracting or Modifying Sent Emails
Communicate Openly with Recipients
When you need to retract or modify a sent email, transparent communication is essential. If the recall attempt fails or isn’t fully successful, make sure to follow up with the recipients directly. Clarify any misunderstandings and provide the corrected information promptly.
Sending a clear correction or apology that references the original message can help maintain professionalism and trust. This approach is particularly important since some recall attempts may notify recipients that a message was withdrawn. This notification can pique curiosity or cause confusion if not properly addressed.
Check Your Settings Regularly
To increase your chances of successfully recalling or preventing erroneous emails, regularly review your Outlook settings and organizational policies. Ensure features like Undo Send are configured with an appropriate delay time. Stay informed about whether your IT admin has enabled or restricted message recall abilities, including the recall of messages that have already been read.
Since Microsoft frequently updates its cloud-based recall system, keeping your Outlook client updated will ensure you have access to the latest recall features and receive accurate message recall reports.
Avoid Reliance on Recall Features
Although Outlook’s recall and undo send features offer useful safety nets, they are not foolproof. You should avoid relying solely on them when sending important emails. Instead, develop a habit of thorough message checking before hitting send. Carefully review recipients, attachments, and the content of your email.
Take advantage of Outlook’s built-in Delay Delivery option if available. This feature holds emails in your Outbox for a specified period before sending them automatically. Combining preventative caution with these features will help minimize the need for recalls and reduce the risk of email mishaps.
Conclusion
In summary, Outlook provides powerful tools like recall message and undo send that allow you to unsend or modify emails. However, it’s important to note that both features have their limitations, which should be carefully considered. Always ensure these options are configured proactively to avoid mistakes, and be prepared to communicate openly with recipients if a recall attempt fails.
Above all, cultivate good email habits, such as thoroughly reviewing messages before clicking send, regularly organizing emails in Outlook, and checking your Outlook settings. By combining a cautious approach with Outlook’s recall functionalities, you can reduce errors and maintain a high level of professionalism in your email communications.
