Hi! In some cases, you can recall an email sent from a shared mailbox in Microsoft Outlook, but it depends on how the message was sent and where it was stored. If you sent the email using Send As or Send on behalf of the shared mailbox and the message is saved in your personal Sent Items, you may be able to open the message and use the Recall This Message option. Message recall in Microsoft Outlook only works when both the sender and recipient are using Microsoft Exchange Online or are within the same organization, and the recipient must not have opened the message yet.
If the message was saved only in the shared mailbox Sent Items folder, the recall option is often unavailable. This is because recall actions are tied to the sender’s mailbox rather than the shared mailbox itself. You can review the official Microsoft guidance on message recall here:
