Get LibreOffice to Recognize Your Java Runtime
Install a compatible Java runtime, enable it in LibreOffice, and troubleshoot an empty JRE list without changing unrelated settings.
Sent an email and immediately spotted an error or the wrong recipient? Knowing how to recall a sent email in Outlook can fix the problem before the message is read. The feature only works when both you and the recipient use Microsoft Exchange or Microsoft 365 and the email remains unread. This guide shows the exact steps to use the recall option correctly.
Outlook's recall feature is limited to specific server environments. It requires an Exchange or Microsoft 365 account on both ends and the message must still sit unread in the recipient's Inbox. If the recipient has already opened the email or uses a POP/IMAP account, the recall attempt will fail and you will receive a notification. Before attempting the process, confirm your account type in File > Account Settings > Account Settings and check the Server Settings tab.
Additionally, recall does not work in Outlook on the web or the new Outlook app for Windows. You must use the classic desktop version of Outlook for Windows. Mac users have no native recall option and must rely on the Undo Send delay instead.
In the Outlook desktop app, click Sent Items in the left navigation pane. Scroll or use the search bar at the top to find the email you want to recall. Double-click the message so it opens in its own window rather than the reading pane.
With the message open, go to the Message tab on the ribbon. In the Move group, click the three dots labeled Actions, then select Recall This Message from the dropdown menu.
In the Recall This Message dialog box, select either "Delete unread copies of this message" or "Delete unread copies and replace with a new message." If you choose the second option, click OK and then compose the corrected version in the new window that appears. Click Send.
Outlook sends you a notification email showing whether the recall succeeded or failed. Check your Inbox for this status message. If the recall failed, you can forward a corrected version manually or ask the recipient to ignore the first message.
If the Recall This Message option is missing, the message was sent from a POP/IMAP account or you are using Outlook Web. Switch to the classic desktop client and confirm the account type again. Recipients using Gmail or other non-Exchange services will always see the original message.
Another frequent problem occurs when the recipient has already opened the email or uses automatic preview. In these cases the recall fails silently for them. Set a short Undo Send delay in File > Options > Mail > Undo Send to catch mistakes before they leave your Outbox in the future.
Keep in mind that even successful recalls leave a trace in the recipient's mailbox if they have already moved or printed the message. Always double-check the content before sending when possible.
No. The recall feature is not available in Outlook for Mac. Use the Undo Send setting with a delay of up to 30 seconds instead.
No. Recipients must also be on Exchange or Microsoft 365. Messages sent to external addresses cannot be recalled.
The recall fails and Outlook notifies you. The original message remains in the recipient's Inbox.
Mastering how to recall a sent email in Outlook requires the right account type and the classic desktop app, but the process takes only a few clicks when conditions are met.
