Mastering Outlook: How to Use the Email Recall Feature Effectively

  • Thread Author
If you've ever hit "Send" on an email and instantly experienced an "Oh no!" moment, you're not alone. Whether it’s because you’ve attached the wrong file, written something unflattering about your boss in a message meant for them, or accidentally sent sensitive information to the wrong recipient, Microsoft Outlook has you covered—sort of. Outlook’s handy email recall feature can save the day in some cases, but there’s a lot more nuance to it than you might think. Let’s break down how this feature works, who can use it, and its many caveats.

What is Outlook’s Email Recall Function?​

The email recall feature in Microsoft Outlook is a built-in tool for unsending emails, provided you meet a laundry list of conditions. Essentially, the recall tool allows users to delete unread copies of an email from recipients’ inboxes—or even replace the message entirely with a corrected version.
Sounds amazing, right? Well, the devil, as always, is in the details. The recall option is not available to everyone, and even those who can access it will need very specific circumstances for the recall to work as intended.

Who Can Use the Email Recall Feature?​

Here's the first hurdle: the recall functionality is not universally available to all Outlook users. You must meet the following requirements:
  • Account Type:
  • You must have either a Microsoft Exchange or Microsoft 365 (formerly Office 365) account. Free Outlook.com accounts or standard Microsoft accounts won’t cut it. That means if you’re sending emails from your @hotmail.com address, this tool isn’t for you.
  • If your organization is using POP or MAPI email servers, recall won’t work either. (These are outdated or minimalistic methods of email communication compared to Exchange servers.)
  • Recipient’s Email:
  • The recipient also needs to be within the same work or school organization and must be using Outlook on the same Exchange-enabled server. In other words, you can’t recall an email sent to someone using Gmail, Yahoo, or another email provider. Interwoven corporate bubbles only!
  • Timing Is Everything:
  • The recipient must not have opened the email yet. As soon as an email has been opened, the recall attempt will fail.
  • Platform:
  • Recall does work on the new Outlook app for Windows and Outlook on the web for organizations. However, Outlook.com (the “lite” version) and the new Outlook for Mac do not support the feature (yet). If you’re using one of the web-based options or working in macOS, you’re out of luck.

Step-by-Step: Recalling an Email in Outlook​

If you’re part of the lucky few who meet all these prerequisites, congrats—you get to try the email recall feature! Here’s how you can unsend an email in different versions of Outlook:

New Outlook App (Windows) & Outlook Web Version

This is the easiest method by far:
  • Go to your Sent Items folder.
  • Double-click the email you want to recall (it needs to open in a separate window).
  • In the ribbon menu, click Recall Message, then confirm.
  • Check your inbox for a recall status update to see if the action was successful, pending, or failed.

Classic Outlook App (Windows)

Classic Outlook offers extended options, including the ability to replace your recalled email:
  • Navigate to the Sent Items folder.
  • Open the email by double-clicking it.
  • Depending on your ribbon layout:
  • For Classic Ribbon, go to the Message tab → ActionsRecall This Message.
  • For Simple Ribbon, find the three-dot menu (...) and select ActionsRecall This Message.
  • Choose to either:
  • Delete unread copies of the email, or
  • Delete unread copies and replace them with an updated version.
  • (Optional) Check the box to receive an update on the recall's success.
  • Confirm the action and wait. Reports on recall success are typically returned within 30 seconds, but for large-scale emails, it might take up to 30 minutes.

What Happens Next?

  • If Successful: The recall or replacement happens silently (though recipients using non-Outlook clients might still receive an awkward “reported recall attempt” notification).
  • If Failed: Failures are usually due to one of the many caveats mentioned earlier, such as the recipient opening the email or using an incompatible email client. Failures will also generate a notification.

Limitations and Quirks​

The recall feature is handy, but it’s no magic wand. There are a few major hurdles and potential pitfalls to keep in mind:
  • Recipient Notification: Even when successful, recipients may get a ping about your recall attempt. This adds, shall we say, an awkward dynamic to the situation (especially if that email was about them!).
  • No Guarantee of Success: Failures happen often, largely due to email incompatibility or timing issues.
  • Mac Support: Recall isn’t yet supported on the new Outlook for Mac. Bummer for those keeping it Apple-aligned!

Broader Implications for Everyday Users & IT Pros​

For businesses:
  • This feature can save employees from public-relations disasters or miscommunications.
  • IT admins should make sure their systems are configured with Microsoft Exchange to enable this feature and support employees.
For individuals:
  • If you’re on the free tier of Outlook or working from Mac, consider upgrading to a Microsoft 365 account if recall feels like a must-have.

Alternatives to Email Recall: A Contingency Plan​

If the recall feature isn’t available, or your situation doesn’t fit its constraints, don’t despair. Here are some additional strategies to reduce “mis-send” risks:
  • Delayed Sending: Configure Outlook to delay sending emails by a few minutes. It gives you some breathing room to make last-minute changes.
  • Encryption Tools: For highly sensitive emails, use encryption tools or services to add an extra layer of security. This ensures that only the right recipient can open them—no recall needed.
  • Double-Check Recipients: Just like looking both ways before crossing the street, take a second glance before hitting “Send.” It’s preventative medicine for email woes.

Final Thoughts: A Mixed Blessing?​

Microsoft Outlook’s recall feature is a lifesaver for users who meet its stringent criteria, but it’s not without its challenges. By understanding how it works—and what limits it—you can use it effectively when needed. And for everyone else? Alternatives like delayed sending can still save you from the most disastrous of email blunders.
