- 在他们的Outlook(Outlook)桌面客户端
上打开召回请求。
此外，收件人的电子邮件帐户不得有任何将电子邮件转发、修改或转移到另一个地址(transfers emails to another address)的规则。遗憾的是，您无法取消发送或撤回发送到第三方电子邮件客户端（如Gmail、Yahoo邮件等
）地址的电子邮件。
还有一件事：如果您的电子邮件帐户使用邮局协议 (POP)(Post Office Protocol (POP))或消息应用程序编程接口 (MAPI)(Messaging Application Programming Interface (MAPI))协议

How to Unsend an Email in Outlook
The Outlook wеb client allows yоu tо unsend an email for up to ten sесonds after hitting the send bυtton. In the Outlook desktop app, you can “recall” a sent email and have it deleted from the recipient’s inbox. Sadly, the Outlook mobile app (Android and iPhone) doesn’t have the undo send feature.
This tutorial covers everything you need to know about unsending and recalling Outlook email messages on your computer.
How to Unsend Emails in the Outlook Web Client
To unsend emails in the Microsoft Outlook web client, you must first enable the “Undo send” feature. Open Outlook in your web browser, sign in to your email account, and follow the steps below.
Enable Outlook Undo Send Feature in Windows
- Select the three-dot icon next to your profile picture and select Settings.
- Select View all Outlook settings at the bottom of the quick settings menu.
- Select Email on the sidebar, open the Compose and reply tab, and scroll to the “Undo send” section. Move the slider to select your preferred number of seconds (10 seconds max) and select Save.
Close the settings menu and send a test email to confirm if the unsend feature works. When you hit the Send button after composing an email, a “Sending” notification pops up in the bottom-left corner. Select Undo to unsend the email.
Remember that you have ten seconds to unsend the email. So, select the Undo button quickly before the pop-up disappears.
Enable Outlook Undo Send Feature on Mac
Outlook for macOS allows up to 20 seconds to unsend an email. Here’s how to configure Outlook’s “Undo Send” feature on your MacBook.
- Open Outlook, select Outlook on the menu bar, and choose Preferences.
- Select Composing in the “Email” section.
- Select the plus icon to set the “Undo Send” period to your preference.
To unsend an email, select Undo on the “Sending…” pop-up within 20 seconds.
If you missed the chance to unsend the message, use the Outlook desktop app to recall the email from the recipient’s inbox.
How to Unsend or Recall Emails in the Outlook Desktop App
Outlook for Windows has a recall feature that allows you to retrieve and edit an email for up to 120 minutes after sending it. When you recall an email, Microsoft unsends the mail and deletes it from the recipient’s inbox.
To successfully recall an email in Outlook, you must:
- Use a Microsoft 365 or Outlook.com account.
- Be on the same Microsoft 365 or Microsoft Exchange server as the recipient.
- Be in the same organization as the recipient.
- Open the recall request on their Outlook desktop client.
Additionally, the recipient’s email account must not have any rule that forwards, modifies, or transfers emails to another address. Unfortunately, you cannot unsend or recall emails sent to addresses on third-party email clients like Gmail, Yahoo mail, etc.
One more thing: you cannot unsend emails in Outlook if your email account uses the Post Office Protocol (POP) or Messaging Application Programming Interface (MAPI) protocol.
Follow the steps below to recall messages sent to the wrong person in your Outlook outbox.
- Launch the Outlook app, open the Sent Items folder, and double-click the email you want to recall. Outlook will open the email in a new window.
- Select File on the menu bar.
- Select Info on the sidebar, scroll to “Message Resend and Recall,” and open the Resend or Recall drop-down menu.
- Select Recall This Message.
Alternatively, open the email, select Actions on the ribbon bar, and select Recall this Message.
- Select Delete unread copies of this message and select OK to recall the email. We recommend choosing the Tell me if recall succeeds or fails for each recipient checkbox so you get notified if the recall succeeds (or not).
If the recipient uses Microsoft Exchange or Microsoft 365 and you’re in the same organization, Microsoft deletes the email you recalled from their inbox. If the recipient uses a third-party email provider, or if their email is outside your organization, they’ll only receive a message that you’d like to recall the email you sent earlier.
The “Delete unread copies and replace with a new message” option allows you to edit and resend an email. Microsoft then replaces the original email with the edited email in the recipient’s mailbox. This option is perfect for fixing typos and incorrect information in emails.
