How to Recall an Email in Outlook: A Complete Guide

You hit send, and then your stomach drops. Maybe you sent the message to the wrong person. Maybe there was a typo in the subject line, or you attached the wrong file. Whatever the reason, you need that email back.

The good news is that Microsoft Outlook includes a message recall feature that can pull back a sent email before the recipient reads it. The not-so-good news is that it only works under specific conditions, and there are a few things you need to know before relying on it.

In this guide, we will walk you through exactly how to recall an email in Outlook, when it will actually work, what to do when it will not, and alternative options that give you more control over sent messages.

Why You Might Need to Recall an Email

Mistakes happen, and email is one of the most common places they show up. A quick reply sent to the wrong thread, confidential information shared with the wrong group, or an unfinished draft that got sent too early can all create real problems for your business.

For small and midsize businesses, these kinds of errors can lead to awkward client interactions, compliance concerns, or internal confusion. Knowing how to recall a message quickly can save you time, protect your reputation, and prevent unnecessary follow-up.

How Email Recall Works in Outlook

Outlook's recall feature works by sending a request to the recipient's mail server to delete the original message from their inbox. If conditions are right, the message is removed before they ever see it. If conditions are not right, the recall fails and the recipient may even receive a notification that you tried to recall the message.

It is important to understand that recall is not the same as "unsend." It is a server-side request, and its success depends on several factors that are outside your control.

Requirements for a Successful Recall

For an email recall to work in Outlook, all of the following conditions must be met:

• Both you and the recipient must be using a Microsoft 365 work or school email account within the same organization [1]. Recall does not work with personal email accounts (Gmail, Hotmail, Outlook.com) or any external email provider.
• The recipient must be using the Outlook desktop app for Windows. While recall is technically available in the new Outlook for Windows and Outlook on the web, its reliability is highest with the desktop app for Windows, and it does not work with Outlook for Mac or Outlook mobile [1].
• The recipient must not have read the message yet. If they have already opened the email, the recall will fail [1].
• The message must still be in the recipient's Inbox folder. If a rule has moved it to another folder, the recall will not work [1].

If any of these conditions are not met, the recall will fail. In many cases, the recipient will see both the original message and a notification that you attempted to recall it, which can draw more attention to the mistake than simply sending a correction.

How to Recall an Email in Outlook (Desktop App)

Follow these steps to recall a sent message using the classic Outlook desktop application on Windows [1]:

1. Open your Sent Items folder

In the folder pane on the left, select Sent Items. Double-click the message you want to recall to open it in a separate window. You must open the message in its own window for the recall option to appear.

2. Go to the Message tab

With the message open, on the Message tab, in the Actions group, click Actions, and then click Recall This Message.

3. Choose your recall option

A dialog box will appear with two options:

• Delete unread copies of this message: This removes the email from the recipient's inbox if they have not read it yet.
• Delete unread copies and replace with a new message: This removes the original and lets you send a corrected version in its place.

4. Check the "Tell me if recall succeeds or fails for each recipient" box

It is recommended to enable this option so Outlook sends you a notification about whether the recall was successful for each recipient.

5. Click OK

Outlook will process the recall request. You will receive a Message Recall Report in your inbox shortly thereafter, which will indicate whether your recall has succeeded, is pending, or failed [1].

Note: The recall option is only available in the Outlook desktop app for Windows. It is not available in Outlook for Mac, Outlook on the web, or the Outlook mobile app [1].

How to Recall an Email in the New Outlook for Windows

If you are using the new Outlook for Windows (the updated version that Microsoft is rolling out to replace the classic desktop app), the recall process is slightly different:

Follow these steps to recall a sent message in the new Outlook for Windows [1]:

1. Open your Sent Items folder

Select Sent Items in the left folder pane, then double-click the sent message to open it in a separate window.

2. Select "Recall Message"

From the ribbon, select Recall Message, then select OK in the confirmation dialog box.

3. Check the Message Recall Report

Shortly thereafter, you will receive a Message Recall Report in your inbox. Select the link in that message to see whether your recall has succeeded, is pending, or failed [1].

The new Outlook recall feature works similarly to the classic version, but Microsoft has been improving its reliability with server-side processing. However, the same fundamental limitations apply: both parties need to be on Exchange or Microsoft 365, and the message must be unread.

What to Do When Recall Fails

Recall fails more often than it succeeds, especially when you are emailing people outside your organization. When that happens, here are your best options:

Send a Follow-Up Correction

The simplest and most professional approach is to send a brief follow-up email acknowledging the error. Keep it short and direct:

"Hi [Name], please disregard my previous email. I've attached the correct version of the document below. Apologies for the confusion."

Most people understand that mistakes happen. A quick, honest correction is almost always better than hoping the recall worked silently.

Use Outlook's "Undo Send" Delay Feature

If you find yourself recalling emails frequently, a better long-term solution is to set up a send delay. This gives you a short window after clicking send to cancel the message before it actually leaves your outbox.

To set up a send delay in classic Outlook:

1. Go to File then Manage Rules & Alerts.
2. Click New Rule.
3. Select Apply rule on messages I send and click Next.
4. Click Next again without selecting conditions (this applies the rule to all sent messages).
5. Select defer delivery by a number of minutes.
6. Set the delay to 1 or 2 minutes and click Finish.

This creates a buffer period where every outgoing email sits in your Outbox for the specified time before sending. During that window, you can open the message, make changes, or delete it entirely.

To set up Undo Send in Outlook on the web:

1. Go to Settings (gear icon) then Mail then Compose and reply.
2. Find the Undo send option.
3. Set the delay to 5 or 10 seconds.
4. Click Save.

After clicking send, you will see an "Undo" option at the bottom of the screen for the duration of your delay window.

Recall vs. Undo Send: Which Should You Use?

Understanding the difference between these two features will help you choose the right approach for your situation.

For most situations, setting up an Undo Send delay is the more reliable option. It prevents mistakes before they happen rather than trying to fix them after the fact.

Common Questions About Recalling Emails in Outlook

Can I recall an email sent to someone outside my organization?

No. The recall feature only works when both the sender and recipient are using Exchange or Microsoft 365 within the same organization. For external recipients, your best option is to send a follow-up correction.

Does recall work in Outlook on the web or Outlook mobile?

The classic recall feature is only available in the Outlook desktop app for Windows. However, Outlook on the web offers an Undo Send feature that works as a short delay after clicking send. The new Outlook for Windows also supports recall with improved server-side processing.

Will the recipient know I tried to recall a message?

If the recall fails, the recipient may receive a notification saying you attempted to recall the message. This can actually draw more attention to the original email, so consider whether a simple follow-up correction might be a better approach.

Can I recall a message if the recipient has already read it?

No. Once the recipient has opened the email, the recall will fail. The message must be unread and still in their Inbox folder for the recall to succeed.

How long do I have to recall a message?

There is no official time limit for attempting a recall, but the sooner you act, the better your chances. The longer you wait, the more likely the recipient has already read the message or moved it to another folder.

Does recall work with Microsoft Teams?

No. The recall feature is specific to Outlook email. However, in Microsoft Teams, you can delete or edit sent messages directly in a chat or channel conversation by right-clicking the message and selecting Delete or Edit.

Tips to Avoid Needing to Recall Emails

Prevention is always better than trying to undo a mistake. Here are a few habits that can help you avoid email errors in the first place:

• Set up a 1-2 minute send delay using the Undo Send feature or an Outlook rule. This is the single most effective safeguard against accidental sends.
• Double-check the To, Cc, and Bcc fields before sending, especially when replying to threads with multiple recipients.
• Use the "Reply" button carefully. Make sure you are replying to the right person and not accidentally hitting "Reply All."
• Attach files before writing the body. If you reference an attachment in your email, add it first so you do not forget.
• Proofread your message. Take 10 seconds to re-read the email before sending. A quick scan can catch typos, tone issues, or missing information.
• Draft sensitive emails offline. For important or sensitive messages, compose them in a draft and come back to review before sending.
