Recall only works on unopened messages in the Outlook desktop app if the message hasn’t been opened, and both people are part of the same Microsoft Exchange server. To recall an email, find it in “Sent Items” in your email account, and click “File.” Select “Info” on the blue column, then click “Resend or Recall,” and “Recall This Message.” Make sure “Tell me if recall succeeds or fails for each recipient” is selected (this will send you a message telling you whether the recall worked or not), then click “Delete unread copies of this message.” If you’d rather edit the message and resend it when Outlook recalls the old version, click “Delete unread copies and replace with a new message” instead. How to Recall an Email in Outlook Using the Built-in Recall Feature Luckily, the native recall feature isn’t the only way to recall an email in Outlook. It will only work between two Outlook users on the Microsoft Exchange server, and even then it’s easy for savvy users to disable. Yet, like most recall tools, Outlook’s function has major limits. While some users might think such a feature is something that only Gmail has, Outlook has natively had the ability to recall an email for years. Fortunately, with an email recall function you can take the message back - ideally before your recipient even reads it. Instead of an awkward moment, you’ve created a permanent record. If there’s anything worse than putting your foot in your mouth in a conversation, it’s doing it over email.
