How to Recall an Email in Outlook on Mac

To recall an email in Outlook on Mac, select Sent in the folder pane, double-click the message to open it in its own window, select Recall on the ribbon and confirm with OK. Recall works only when you and the recipient both use Microsoft 365 work or school accounts in the same organization, and it needs the new Outlook for Mac, version 16.94 or later.

This guide covers the requirements, the exact steps, how to read the Message Recall Report, why a recall fails, and what to do when your account cannot recall messages at all.

Requirements to recall an email in Outlook for Mac

Outlook for Mac can recall a message only when four conditions are met. Check them before you try, because a recall outside these conditions fails, and you only find out from the Message Recall Report.

• Account type: you and the recipient both have a Microsoft 365 work or school account in the same organization.
• No personal accounts: messages sent to or from Gmail, Hotmail, Outlook.com or live.com addresses cannot be recalled.
• App version: Outlook for Mac 16.94 (Build 25010522) or later. Recall is not supported in legacy Outlook for Mac.
• Admin policy: your Exchange Online administrator has not turned message recall off for the organization.

Microsoft lists Outlook for Microsoft 365 for Mac, Outlook 2024 for Mac and Outlook 2021 for Mac as supported editions. Check the version number in Outlook's About window before you rely on recall. If you use a work account, your organization may manage Outlook for Mac profiles and updates for you, so ask IT if the version is older than 16.94.

How to recall an email in Outlook on Mac, step by step

Recalling an email in Outlook on Mac takes three steps and starts from the Sent folder, not the preview pane.

1. Select Sent in the folder pane and double-click the message to open it in a separate window.
2. On the ribbon of that window, select Recall, then select OK in the confirmation window. Alternatively, Control-click the message in the Sent list and choose Recall from the shortcut menu.
3. Wait for the Message Recall Report in your inbox and open its link to see the result for each recipient.

If the Recall button is missing from the ribbon, add it through the toolbar customization option described in Microsoft's guide to customizing the toolbar in Outlook for Mac. If the button is still missing after that, you are most likely on legacy Outlook, a build older than 16.94 or a personal account.

Microsoft's official steps are on the support page Recall an email message in Outlook for Mac.

What the Message Recall Report tells you

The Message Recall Report is the only reliable way to know whether an Outlook for Mac recall worked. Exchange Online sends it to your mailbox within a few minutes, from [email protected], and it contains a link to a status page that shows each recipient as succeeded, pending or failed.

Behind the scenes, Outlook sends a recall request that Exchange Online intercepts. The service then tries to hard-delete the original message from each recipient's mailbox, and it keeps trying for up to 24 hours. Status for most recipients appears within minutes, while messages sent to many people can take longer.

Two practical points follow from this:

• Do not assume the message is gone until the report says succeeded for that recipient.
• If no report arrives, your admin can check the recall with message trace, and should make sure the report sender is not blocked by a mail rule.

Why an Outlook for Mac recall fails

An Outlook for Mac recall usually fails because the message left the boundary of your Exchange Online organization or because a tenant setting blocks it. Microsoft documents these cases:

Recipients are not notified of a recall by default, but administrators can enable recipient alerts. Either way, treat recall as damage control, not a guarantee.

Admin settings that control message recall

Exchange Online administrators control recall for the whole organization with the Set-OrganizationConfig cmdlet, so a recall that fails for every recipient often points to a tenant setting rather than a problem in Outlook for Mac.

• MessageRecallEnabled turns message recall on or off.
• RecallReadMessagesEnabled decides whether messages the recipient has already read can be recalled.
• MessageRecallAlertRecipientsEnabled notifies recipients when a message is recalled (off by default).
• MessageRecallMaxRecallableAge sets how old a message may be (default 365 days, configurable from 5 minutes to 10 years).

Cross-tenant recall needs a separate setting on the receiving side. Full details are in Microsoft's documentation on cloud-based message recall in Exchange Online. If you are a user, share this list with IT when recalls keep failing.

What to do if you cannot recall the email

If Outlook for Mac cannot recall the message, send a short follow-up email that corrects the mistake. Keep it brief: state what was wrong, attach the missing file or the corrected figures, and ask the recipient to disregard the earlier version.

Personal accounts such as Outlook.com, Hotmail and Gmail never support recall. For those, Microsoft points to Undo Send, a short send delay available in Outlook.com and the new Outlook for Windows, which only helps if you set it up before you send. Gmail has a similar option, explained in our guide to undoing sent emails in Gmail.

For accidental sends of sensitive data to an external address, recall will not help. Contact the recipient directly and, in a work setting, report it to your IT or security team.
