We’ve all hit ‘send’ too quickly, realising an error moments later. Indeed, it’s a feeling that can instantly trigger a wave of panic. Furthermore, in the professional landscape of Australian businesses, sending an incorrect email can have significant consequences. Specifically, miscommunication can lead to costly misunderstandings, data breaches can compromise sensitive information, and reputational damage can erode hard-earned trust. However, Outlook offers a potential lifeline: the email recall feature. Therefore, it’s crucial to understand that this feature comes with limitations, and success isn’t always guaranteed.
Moreover, this article will guide you through how to use this feature effectively, outlining its limitations and providing best practices tailored for Australian businesses. Additionally, we will explain how to recall an email on different devices and platforms like Mac, iOS, Android etc., ensuring you’re equipped to handle those ‘oops’ moments, wherever they occur.

Understanding Outlook’s Email Recall Feature
What is Email Recall?
Outlook’s email recall feature allows users to attempt to delete or replace an email after it has been sent. This feature is particularly useful in professional settings where errors can lead to miscommunication or data privacy concerns. By recalling an email, you can prevent recipients from seeing incorrect information, missing attachments, or unintended messages. However, this function has several conditions that must be met for it to work successfully.
How Does Email Recall Work?
When you recall an email in Outlook, the system attempts to remove the message from the recipient’s inbox before they open it. Instead of simply deleting the email from all mailboxes, Outlook sends a request to the recipient’s Microsoft Exchange or Microsoft 365 server. If the recipient has not yet opened the email, Outlook will attempt to delete it or replace it with a corrected version. However, if the email has already been read, the recall request will fail. Additionally, if the recipient’s inbox is configured to process messages manually, the recall may not work as expected.
Can You Recall an Email Once It Has Been Sent?
The success of recalling an email in Outlook depends on several key factors:
- Recipient Must Be Using Outlook in the Same Microsoft Exchange or Microsoft 365 Organisation
The recall feature only works if both sender and recipient are part of the same organisation using Microsoft Microsoft 365 or Exchange environment. - Recipient Must Not Have Opened the Email
If the recipient has already read the email, the recall attempt will fail. Outlook cannot force an email to be deleted once it has been opened. - Recall Success is Not Guaranteed
Even if the recipient has not opened the email, other factors—such as email rules or inbox settings—can impact recall success. So, recall success is not guaranteed, even if all these conditions are met. - Email Sent to an External Address Cannot Be Recalled
If an email was sent to an external email address, such as Gmail or Yahoo, the recall feature will not work. This limitation makes it crucial to double-check recipients before sending emails. - Recipient’s Outlook is Offline or Processing Emails Manually
If the recipient’s Outlook is offline when the recall request is made, the email might still be delivered when they reconnect. Additionally, if their email is set to process messages manually, the recall request might not be processed in time. - Email Was Moved by a Rule
If the recipient has set up inbox rules that automatically sort emails into different folders, the recall attempt might fail. This happens because Outlook can only recall emails that remain in the recipient’s Inbox. - Not Available for IMAP or POP3 Accounts
The recall feature does not work for emails sent via IMAP or POP3 accounts. Many personal and business email services use these protocols, making recall impossible for those users.
Why This Matters for Australian Businesses
For Australian businesses, managing email errors is essential, especially when handling sensitive customer data. The Australian Privacy Principles (APPs) require organisations to take reasonable steps to protect personal information and correct errors promptly. If an email containing confidential data is sent to the wrong recipient, businesses must act quickly to mitigate potential breaches. Since Outlook’s recall feature is not foolproof, companies should also implement best practices, such as email encryption, pre-send delay settings, and clear communication protocols.
In the next section, we will walk through how to recall an email in Outlook step by step to help Australian businesses minimise email-related risks.
How to Recall an Email in Outlook (Desktop App)
Accessing the Recall Feature
- Firstly, open the ‘Sent Items’ folder in your Outlook application.
- Then, locate and double-click the email you want to recall.
- Next, ensure the email opens in its own window, not just the reading pane.
- After that, look for the ‘File’ tab in the top-left corner and click on it.
- Subsequently, select ‘Info’ from the menu.
- Following this, you should see a ‘Message Resend and Recall’ section.
- Moreover, click on ‘Recall This Message…’.




Choosing Recall Options
- Now, you’ll be presented with two options:
- ‘Delete unread copies of this message’
- ‘Delete unread copies and replace with a new message’
- Specifically, in the first option, Outlook will attempt to delete the original email from the recipient’s inbox.
- Conversely, the second option allows you to edit the original email and send a corrected version.
- Additionally, you can choose to ‘Tell me if recall succeeds or fails for each recipient’ by checking the box.
- Then, click ‘OK’.
Understanding Recall Outcomes
However, remember that the outcome can vary. Therefore, it is best to check the recall status message that outlook provides.
- Successful recall: You’ll receive a success message.
- Failed recall: You’ll receive a message stating the recall failed.
- Partial recall: Some recipients received the recall, and others did not.

Troubleshooting Tips
- If you encounter issues, such as a missing ‘Actions’ or ‘Message Resend and Recall’ button, here are some troubleshooting tips:
- Firstly, confirm that you are using a Microsoft Exchange or Microsoft 365 account.
- Secondly, verify that the recipient is within the same organisation.
- Thirdly, ensure that the email has not been opened.
- Furthermore, if the email has been moved to a different folder by a rule, the recall will fail.
- Finally, try restarting Outlook or your computer, as this can sometimes resolve temporary glitches.
- Indeed, if you are still experiencing issues, contact your IT support, as they can provide specific assistance based on your organisation’s configuration.
Recall on Different Platforms
Outlook’s email recall feature is primarily available on the Windows desktop version. However, users on other platforms, such as Outlook on the Web (OWA), Mac, iPhone, and Android, have limited or no access to this function. Below, we’ll explain how recall works—or doesn’t—on each platform and suggest alternative solutions for Australian businesses.
1.Outlook on the Web (OWA – Outlook.com & Microsoft 365 OWA)
Can You Recall an Email in Outlook Web?
It is crucial to understand that the traditional “Recall This Message” feature, as found in the desktop Outlook application, is generally not available in the modern Outlook on the Web (Outlook.com and Microsoft 365 OWA).
“Undo Send” Feature:
Although traditional recall is unavailable, Outlook on the Web offers an “Undo Send” feature that allows users to stop an email from being sent. However, this feature is time-sensitive and only works within a short period after clicking “Send.”
How to Use “Undo Send” in Outlook on the Web
- Immediately after sending an email, look for the “Undo” option that appears briefly at the bottom of the screen.
- Click “Undo” to stop the email from being sent.
Time Sensitivity:
- This feature is time-sensitive, and the “Undo” option disappears after a short period.
- Important: “Undo Send” prevents the email from being sent in the first place, rather than retracting it after it has been delivered.
- Customisation: The time allowed for “Undo Send” can be adjusted in your Outlook on the Web settings.
Interface Differences:
- While the “Undo Send” function is generally available, the exact location and appearance of the “Undo” option might vary slightly depending on your specific version of Outlook on the Web.
- General location: Look for a small notification at the bottom of your browser window immediately after sending an email.
Alternative Solutions:
- For greater control, consider using the “Delayed Send” feature to schedule emails for delivery at a later time.
- Additionally, if you realise an error after the “Undo Send” window has disappeared, send a follow-up email with corrections or an apology.
Avoid Misleading Language:
It is vital to remember that “Undo Send” is not the same as the desktop Outlook’s “Recall” feature.
Adjusting the “Undo Send” Time Limit in Outlook on the Web:
“To adjust the ‘Undo Send’ time limit in Outlook on the Web, follow these steps:
- Firstly, click on the Settings Gear Icon (⚙) in the top-right corner.
- Then, select ‘View all Outlook settings’ at the bottom of the settings pane.
- Next, in the settings menu, select ‘Mail’ and then ‘Compose and reply’.
- After that, scroll down to the ‘Undo send’ section.
- Subsequently, adjust the time delay to your preference (options typically include 5, 10, or up to 30 seconds).
- Finally, click ‘Save’ to apply the changes.
2.Outlook Mobile App (iOS and Android)

Can You Recall an Email in the Outlook Mobile App?
No, email recall is not available in the Outlook mobile app on either iOS (iPhone/iPad) or Android. Microsoft has not included this feature due to technical limitations related to how emails are processed on mobile devices.
Alternative Solutions:
If you send an incorrect email from your mobile device, the best course of action is to send a follow-up apology or correction email.
3. Outlook on Mac
How to Recall an Email in Outlook on Mac?
The recall process in Outlook for Mac is similar to the Windows desktop version but with a slightly different interface.
Key Points:
- Recall is Available (with Limitations): The ability to recall emails in Outlook for Mac is now available. However, it’s important to note that, as with the Windows version, it has limitations.
- Requirements: The most crucial requirement is that both the sender and the recipient must be using Microsoft 365 or Microsoft Exchange accounts within the same organisation. Otherwise, recall is not possible for emails sent to external addresses (like Gmail or Yahoo).
- Evolution of the Feature: The recall feature in Outlook for Mac has been a feature that has been developed and rolled out over time. Therefore, some older information might be outdated.
General Steps (with variations):
The core concept remains the same, but the UI can differ. Here’s a general outline, but always refer to your specific Outlook for Mac version:
- Open the “Sent Items” Folder:
- Locate and open the “Sent Items” folder to find the email you want to recall.
- Open the Email:
- Double-click the email to open it in its own window. This is a crucial step; you can’t recall from the reading pane.
- Locate the “Recall” Option:
- This is where variations can occur depending on your Outlook for Mac version:
- Ribbon: In some versions, you might find a “Recall Message” option within the ribbon interface (look for a “Message” tab or similar).
- Context Menu: You might be able to right-click (or Control-click) on the sent message to bring up a context menu, where you can find a “Recall” option.
- This is where variations can occur depending on your Outlook for Mac version:
- Choose a Recall Option:
- You’ll generally be presented with similar options as in Windows:
- “Delete Unread Copies of This Message”: This attempts to remove the email from the recipient’s inbox if they haven’t opened it.
- “Delete Unread Copies and Replace with a New Message”: This allows you to send a corrected version of the email.
- You’ll generally be presented with similar options as in Windows:
- Confirm and Send Notifications:
- You can typically choose to receive a report on whether the recall was successful or failed.
4. Outlook on iPhone
Can You Recall an Email in Outlook on iPhone?
No, email recall is not possible on the iPhone version of Outlook.
Why Is Recall Unavailable on iPhone?
- The Outlook mobile app, including the iPhone version, does not have direct access to the same server-side recall functionality as the Windows or Mac desktop applications.
- Mobile devices generally process and transmit emails differently. Once an email is sent from the Outlook mobile app, it is typically delivered to the recipient’s server almost immediately.
Alternative Solutions for iPhone Users:
- Follow Up with a Correction Email. In other words, if a mistake is made, quickly send another email explaining the issue.
Timing and Success Factors
Can You Recall an Email Once It Has Been Sent?
Yes, but with limitations. Outlook allows email recall only under specific conditions.
Key requirements:
- Firstly, both sender and recipient must be using Microsoft Exchange or Microsoft 365 accounts within the same organisation. This means it’s primarily for internal company emails. You cannot recall emails sent to external addresses like Gmail, Yahoo, or personal Outlook.com accounts.
- Secondly, the email must be unread in the recipient’s inbox.
- Thirdly, the recall feature is only available on Outlook for Windows (not Mac, Web, or Mobile)
- Lastly, even within an Exchange environment, other factors can affect recall success. For example, if the recipient has rules or filters that move the email to a different folder, the recall might not work.
How Long Do You Have to Recall an Email in Outlook?
There is no fixed time limit for recalling an email in Outlook. However, the sooner you attempt the recall, the higher the chances of success.
Key Timing Factors:
- Immediate Action is Best → Recall is most likely to succeed if the recipient has not yet opened the email.
- Server Latency Matters → Sometimes, delays in Microsoft Exchange servers can affect how quickly the recall request is processed.
- Recipient’s Outlook Settings Play a Role → For example, if their Outlook is set to process emails manually, recall may be delayed or even fail.
How Long Does It Take to Recall an Email in Outlook?
The recall attempt itself is initiated instantaneously. In other words, the moment you click “Recall This Message,” Outlook immediately sends the recall request to the Exchange server. The server then processes the request, which involves checking the status of the email in each recipient’s inbox. So this process can take time, especially if there are many recipients or if the server is busy.
- If Successful: The email will be deleted or replaced, and you will receive a confirmation notification.
- If Unsuccessful: The original email remains in the recipient’s inbox, and they might receive a notification that you tried to recall it.
- Partial Success Possible: If the email was sent to multiple people, recall might succeed for some recipients but fail for others.
Factors Affecting Recall Success
Several technical and user-related factors determine whether an email recall will work. Consequently, it is important to understand these limitations:
✅ Recipient’s Outlook Version → Recall works only if the recipient is using Microsoft Outlook on Windows and is part of the same Microsoft Exchange or Microsoft 365 organization.
✅ Recipient’s Server Settings → If the recipient’s mailbox is configured to process messages manually, recall may not execute immediately.
❌ Recipient Has Already Opened the Email → Once recipient read the email, recall automatically fails.
❌ Recipient Moved the Email → If the recipient has set up rules to automatically move emails to another folder, recall will not work.
Minimising Recipient Awareness
How do I recall an email in Outlook without recipients knowing?
It’s unfortunately nearly impossible to guarantee complete secrecy when attempting to recall an email.
Explanation:
Firstly, recipients may receive a notification of the recall attempt, even if the recall ultimately fails. This is because Outlook often sends a message to the recipient’s server indicating that a recall has been requested. Therefore, even if the original email isn’t deleted, the recipient might be aware that you tried to retract it.
Alternatives and Best Practices
- Delay Delivery:
- Firstly, set a delay on sending emails to allow time for review.
- In particular, this is useful for critical or sensitive emails, providing a buffer before you send them.
- “Undo Send” Feature:
- Indeed, it is available in Outlook Web.
- Remember, this feature only prevents the email from being sent within a short time frame; it’s not a true recall.
- Drafts and Proofreading:
- Consequently, emphasise the importance of thorough proofreading before sending any email.
- Specifically, double-check recipients, attachments, and the overall message for accuracy and clarity.
- Also, consider having a colleague review important emails before send it.
- Follow-Up Emails:
- Therefore, if recall fails or if you discover an error after sending, send a clear and concise follow-up email correcting the mistake.
- Moreover, a professional apology can mitigate any potential negative impact.
- Email Delay Rules:
- Now, guide on setting a delay before sending emails.
- To do this, in the desktop Outlook app, you can create a rule that delays sending all or specific emails by a set number of minutes.
- For example, go to “File” > “Manage Rules & Alerts” > “New Rule” and follow the prompts.
- Training and Awareness:
- Then, recommend training for employees on email etiquette and best practices.
- This includes training on how to avoid common email errors, how to use Outlook features effectively, and the importance of data privacy.

Conclusion
In summary, we’ve explored the ins and outs of Outlook’s email recall feature, highlighting its significant limitations. Specifically, it’s crucial to remember that recall is most effective within the same Microsoft 365 or Exchange organisation. Also keep in mind that success is never guaranteed. Ultimately, prevention is always better than cure. Indeed, taking the time to ensure accuracy before sending an email can save you from potential embarrassment, miscommunication, and even legal issues, especially concerning Australian data privacy laws.
