Recalling an email in Outlook can work, but only under specific conditions. If the recipient is in the same Microsoft 365 organisation, they haven’t opened the message yet, and both mailboxes are on Exchange, you have a real chance. If any of those conditions don’t apply, the recall will fail silently and the email stays in their inbox. This guide walks you through exactly how to do it, when it will succeed, and what to do when it won’t.

How to Recall an Email in Outlook (Desktop)

These steps apply to the classic Outlook desktop app on Windows with a Microsoft 365 or Exchange account.

1. Open your Sent Items folder.
2. Double-click the email you want to recall to open it in its own window.
3. Go to the Message tab in the ribbon.
4. Click Actions, then select Recall This Message.
5. Choose either Delete unread copies of this message or Delete unread copies and replace with a new message.
6. Tick the box to receive a notification for each recipient if you want confirmation.
7. Click OK.

Note for newer Outlook versions: In the updated Outlook for Windows, the recall option may appear under the three-dot menu or via a Recall Message button near the top of the email. Microsoft has been rolling this out progressively across M365 tenants.

How to Recall an Email in Outlook on the Web

The web version of Outlook (outlook.office.com) now supports message recall for Microsoft 365 accounts.

1. Go to your Sent Items folder.
2. Open the email you want to recall.
3. Click the three-dot menu (…) at the top of the message.
4. Select Recall Message if the option is available.
5. Confirm the action in the dialogue that appears.

If you don’t see the recall option in the web version, your organisation’s settings or account type may not support it.

The “Replace with a New Message” Option

When recalling, you can choose to replace the original email with a corrected version. This is useful if you sent incorrect information rather than the wrong attachment or wrong recipient. Outlook will attempt to delete the original and deliver a new message in its place. The same limitations apply: it only works for unread emails within the same organisation.

When Email Recall Actually Works

Recall is not magic, and it succeeds far less often than people expect. Here are the conditions where it has a real chance of working:

• Both you and the recipient are in the same Microsoft 365 or Exchange organisation
• The recipient has not yet opened the email
• The email is sitting in their inbox, not a subfolder or a rule-filtered location
• The recipient is using Outlook on desktop or web, not a mobile app
• No automatic processing rules have moved or forwarded the message

When all of these line up, recall works well. Outside of that narrow window, you’re dealing with the second option below.

When Recall Won’t Work

This is the part most people find out the hard way. Recall will fail in the following situations:

• External recipients: Anyone outside your organisation cannot have emails recalled. Full stop.
• Already opened: If the recipient has read the email, the recall fails. They will also receive a notification that you tried to recall it, which can be more awkward than the original mistake.
• Mobile apps: Emails opened on iOS or Android mail apps, including the Outlook mobile app, cannot be recalled.
• Gmail, Apple Mail, or third-party clients: Recall only works within the Microsoft ecosystem. Gmail users will receive the recall request as a separate email, and the original stays untouched.
• Shared or delegated mailboxes: Recall behaviour can be unpredictable in shared mailbox scenarios.

What to Do When Recall Won’t Work

Take a breath. A follow-up email sent quickly and professionally handles most situations better than a failed recall attempt.

Keep it short and direct. Something like: “Apologies for the previous email. Please disregard the attachment I sent in error. I’ve included the correct version below.”

If you sent sensitive information to the wrong person, contact your IT team immediately. They may be able to take action at the server level or advise on next steps, particularly if data privacy obligations apply.

How Microsoft Copilot Can Help

If the email you sent had incorrect information and you need to send a correction or apology, Microsoft Copilot can draft it for you in seconds. Open a new email, click the Copilot icon, and describe what happened. Copilot will generate a professional correction email that you can review and send straight away.

This is especially useful when you’re flustered and want to respond quickly without the message sounding panicked or unprofessional. Copilot keeps the tone calm and clear, which is exactly what you need in that moment.

Frequently Asked Questions

Can I recall an email sent from Outlook to Gmail?

No. Email recall only works within Microsoft Exchange or Microsoft 365 environments. Gmail recipients will not have the message removed from their inbox.

Will the recipient know I tried to recall the email?

Yes, if the recall fails, the recipient will typically receive a notification saying you attempted to recall the message. This is worth considering before you try, especially if the situation is sensitive.

How long do I have to recall an email?

There is no fixed time limit, but the sooner you act the better. Once the recipient opens the email, recall is no longer possible. In practice, you have the best chance within the first few minutes of sending.

Does recall work in the new Outlook for Windows?

Yes, Microsoft has added recall functionality to the new Outlook for Windows, though the location of the button may differ from the classic interface. Look for it in the message options or the three-dot menu when viewing a sent email.

What if I sent an email to the wrong person inside my company?

Try the recall immediately. If the recipient hasn’t opened it yet and they’re using Outlook on desktop, it may succeed. Follow up with a direct message or call to make them aware, regardless of whether the recall works.
