How to Recall a Message in Outlook 365

Sending an email by mistake is something that happens to all of us. Whether it’s forgetting an attachment, messaging the wrong person, or making a typo, hitting “Send” too soon can lead to panic. Fortunately, Microsoft Outlook 365 offers a message recall feature that might help undo the error—if you meet certain conditions.


What is the Recall Message Feature in Outlook 365

What Message Recall Does

The recall message feature in Outlook allows you to retrieve an email from a recipient’s mailbox—before they open it. You can also choose to replace the original message with an updated version. This is especially useful when you forget an attachment, send incorrect information, or email the wrong person.

Limitations of Recall

This feature only works under specific conditions:

  • Both you and the recipient must use Microsoft 365 work or school accounts
  • You must belong to the same organization
  • Both users must be using the Outlook desktop application
  • Emails sent to Gmail, Yahoo, or Hotmail accounts cannot be recalled

What Happens When You Recall an Email in Outlook

The Internal Process Explained

When you initiate a recall, Outlook sends a command to the recipient’s mailbox, asking it to delete the unread message. If you choose to replace the message, a new email will be sent.

However, if the original message was:

  • Read before the recall request arrives
  • Moved to another folder
  • Sent to an external address

Then the recall will fail.

Outlook will notify you of the result with a Message Recall Report.


How to Recall a Message in Outlook 365

Using New Outlook Interface

To begin recalling an email in the new version of Outlook,

Open your Sent Items folder on the left side of your mail interface. Find the email you wish to recall and double-click it to open it in a separate window. You must open the full email window for the recall option to appear.

Once the message window is open, look for the Recall Message button in the ribbon at the top. Click it, and a dialog box will appear, confirming whether you want to delete the unread message or delete and replace it with a new one. After you make your choice and select OK, Outlook will process your request.

Shortly after completing these steps, you will receive a Message Recall Report in your inbox. This report will let you know whether the recall was successful, is still pending, or has failed.

Using Classic Outlook Interface

In the classic version of Outlook, you will start the same way by opening the Sent Items folder and finding the message you want to recall. You must double-click the email so that it opens in a new window.

With the message open, navigate to the Message tab. If you’re using the Classic Ribbon, look for the Actions dropdown and choose Recall This Message. If you’re using the Simplified Ribbon, click the More Commands icon—usually represented by three dots—and then hover over Actions and select Recall This Message.

You will see two choices: delete unread copies or delete and replace with a new message. Select your preference, click OK, and follow the prompts. If you’re replacing the message, a new email window will open so you can revise your message before resending.

When the Recall Option Doesn’t Appear

If you do not see the Recall This Message option, it likely means that your email account is not hosted on Microsoft Exchange or the feature is not supported in your version of Outlook. This function is typically limited to Microsoft 365 work or school accounts within enterprise environments.


How Long Does It Take to Recall an Email in Outlook

Typical Timeframes

The good news is that most recall requests are processed very quickly. In most cases, you’ll receive a Message Recall Report in your inbox within 30 seconds to 5 minutes after initiating the request.

Delays with Larger Recipient Groups

If your original email was sent to hundreds or thousands of recipients, you may experience a delay in receiving full recall results. For most cases, the report will be ready in five minutes. However, with larger email groups, compiling the full status can take up to 30 minutes.

Retry Attempts for Failed Deliveries

If the recipient’s mailbox is temporarily unavailable or experiencing delays, Outlook will attempt to retry the recall process. This retry period can extend up to 24 hours before a recall is marked as failed.


How to Track Email Recall Status in Outlook

Viewing the Message Recall Report

Outlook automatically sends a notification email after you initiate a recall. The subject line of this email will begin with “Message Recall Report for message” followed by your original email subject.

Open this message and click the link labeled View Message Recall Report. This link takes you to a report in your browser that shows whether the message was successfully deleted from each recipient’s mailbox.

You may need to log in with your Microsoft 365 account to view this information securely.

Checking Sent Items for Status Updates

You can also return to your Sent Items folder and look for the recall status next to the original email. This method is helpful if the recall notification hasn’t arrived yet or if you want to cross-reference the status manually.

Verifying with the Recipient

In cases where certainty is critical, the most direct method is to ask the recipient whether they received the original email or a recall notification. This isn’t the most subtle approach but can be helpful in urgent or sensitive situations.


Requirements for Successful Recall

Same Exchange Environment

Both the sender and the recipient must use Microsoft Exchange within the same organization. The feature is designed for internal communication only.

Email Must Be Unread

If the recipient opens the email before the recall request is processed, the recall will fail. Timing is crucial.

Use of Outlook Desktop App

Both you and the recipient must be using the desktop version of Microsoft Outlook. Recall does not work in Outlook Web App (OWA) or mobile versions.

Same Organization and Server

The recall must occur between two users on the same Exchange server. If your email travels outside your organization—even if it’s to another company using Outlook—the recall won’t work.


Factors That Affect Email Recall

Recipient’s Outlook Settings

If the recipient has settings that mark emails as read upon preview, Outlook may treat the message as already opened—even if they didn’t read it intentionally. This will cause the recall to fail.

Speed of Reading

If the recipient checks their email frequently or sees it shortly after you send it, the recall won’t arrive in time to delete the original.

Multiple Devices and Auto-Syncing

If the recipient uses multiple devices like a phone and laptop, their email may already sync and mark messages as read, preventing a successful recall.


How to Know if Your Recall Was Successful

Recall Notifications

After initiating a recall, you’ll receive a notification message from Outlook. It will indicate if:

  • The recall succeeded (the original message was not read)
  • The recall failed (the message was already read or moved)

View the Message Recall Report

The report link provided in the email gives a detailed view, especially helpful for large recipient lists. You can see the status for each user in your organization.

Direct Confirmation

In sensitive cases, asking the recipient directly if they received the original message or recall notice may be necessary, especially when confirmation is critical.


Final Thoughts on Recalling Emails in Outlook 365

While Outlook 365’s email recall feature is a powerful tool, it has its limits. Success depends on timing, system compatibility, and user settings. Always double-check your email before sending, especially when dealing with sensitive or critical content.

If a mistake happens, now you know exactly how to recall a message in Outlook 365, how to track its success, and what to expect throughout the process. Understanding the requirements and limitations will give you better control and reduce your email-related stress.
