Free Email Recall Checker
You can only truly recall an email in Outlook with a Microsoft 365 work or school account, and only when the recipient is in your own organization. Everywhere else, including Gmail, Outlook.com, Apple Mail and Yahoo, you only get a short Undo Send window right after you click Send. Answer four questions and this checker tells you which case you are in and exactly what to click.
Runs in your browser. Nothing you choose or type is sent to a server.

Answer questions 1 to 3 to see whether this email can still be recalled.

Frequently asked questions
How do I recall an email in Outlook?
Open Sent Items and double-click the message to open it in its own window. In classic Outlook for Windows, select Message > More Move Actions > Recall This Message (Simplified ribbon: More commands > Actions > Recall This Message), choose to delete unread copies, and select OK. In new Outlook and Outlook on the web, select Recall Message, then OK. It only works with a Microsoft 365 work or school account when the recipient is in your organization.
Can you unsend an email in Gmail?
Only during Undo Send. Gmail holds a sent message for the cancellation period you choose, 5, 10, 20 or 30 seconds, under Settings > See all settings > General > Undo Send. Click Undo in the bottom-left corner, or tap Undo in the Gmail app, before it disappears. Gmail has no recall after that.
Why did my Outlook recall fail?
The most common reasons: the recipient is outside your Microsoft 365 organization (Gmail, Outlook.com or another company), you sent from a personal Outlook.com, IMAP or POP account, or the recipient already opened it and your organization doesn't allow recalling read messages. Messages forwarded manually or by an Inbox rule also can't be recalled. Open the Message Recall Report to see each recipient's status.
Does the recipient know I recalled an email?
Not necessarily. In Microsoft 365, recipients only get a recall notice if your IT admin turned recipient notifications on, which is off by default. They may still have seen the message before the recall ran. A Gmail, Outlook.com or Apple Mail Undo Send happens before delivery, so the recipient never sees anything.
Can I recall an email sent to an external address?
Almost never. Outlook Message Recall works inside your own Microsoft 365 organization; it reaches another company only if that company's admin has turned on cross-tenant recall for your organization. Gmail, Yahoo and Apple Mail can't recall at all. Send a short correction instead, and ask the recipient to delete it if it contained sensitive information.
