Recall a sent message (and why it will probably fail)

Instead of forwarding a message to someone else, I accidentally replied to it.

As this is a bit of an embarrassing mistake, I was wondering if I could “undo” the sending of this message.

Can I recall a message and how can I prevent future mistakes?

Recall this message buttonYes, in theory you can recall a message but the conditions for it to work are so specific that in praxis it hardly ever works as you want it to.

Therefor, in most cases, it might be better to simply sent a short but sincere apology message rather than trying to save face the technical route. This way the recipient won’t get a weird technical message which probably only increases the attention to the message you never wanted to sent.

Before getting down to the nitty-gritty of recalling a message in Outlook, let’s take a look at some methods to prevent future mistakes first.

Prevent recalls

Manage Rules & Alerts buttonMost often, you’ll realize that you are making a mistake the moment that you hit that Send button. If you’re lucky, it is a big message with a large attachment which takes a while to send so you have some time to pry it out of your Outbox folder.

Chances are however that you won’t be that lucky. To counter that, you could create a rule which delays sending all messages for 1 or 2 minutes so you have some time to react without seriously slowing down your regular communications. You can set it up 120 minutes if you want but that might be less practical.

Variations of the rule are also possible to fit your needs. For instance, only delay sending of the message when it is to your boss. Or set an exception so that messages sent with a high priority won’t be delayed.

Detailed instructions for setting up such a rule and other delay techniques can be found in the tip Don’t send emails directly.

When will Recall actually work

Recall Success or Failure? buttonThere are several conditions which must be met for the Recall feature to work:

  • The first condition for Recall to work is that you must be using an Exchange account and the recipient must be within that same Exchange organization as well. In other words; When you are using a POP3, IMAP or account or when the recipient is working for another company, you are out of luck already.
  • The recipient must also be using Outlook to read his/her emails. When a message is being read via Outlook on the Web (OWA) or via EAS on a smartphone or tablet, the recall will not work.
  • The recipient must have an active connection with Exchange. When Cached Exchange Mode is enabled and the recipient is working off-line, the recall process will fail.
  • The original message must arrive in the Inbox folder of the recipient. When it got moved via a rule, recalling the message is not possible.
  • The original message must still be unread and the recipient must open the Recall message before the original message.

You might be lucky and the recipient has the option “Automatically process meeting requests and responses to meeting requests and polls” enabled. In that case, the original message and the recall message could arrive when the user is working in another application with Outlook running in the background and the recall/replace could happen unnoticed (aside from the 2 or 3 New Mail Notifications and only seeing 1 or no new message).

Note: There are still some other specific scenarios for which the recall will fail. For instance; You also won’t be able to recall the message when it was sent from a Delegate or Shared Mailbox. It has to be the primary Exchange mailbox of your Exchange account.

The Recall process

Do you think your case meets all the conditions? Are you feeling lucky and still want to use the Recall feature?
Here is how to set things in motion and monitor its success.

  1. Double click on your sent message to open it in its own window.
  2. Execute the Recall This Message… command:
    • Office 365 (Single Line Ribbon)
      Message tab-> click on the ellipsis (3 dots all the way on the right)-> Actions-> Recall This Message…

      Recall This Message... command in the Single Line Ribbon

    • Outlook 2007 / 2010 / 2013 / 2016 / 2019 / Office 365 (Classic Ribbon)
      Message tab-> group: Move-> Actions-> Recall this Message…

      Recall This Message... command in the Ribbon

  3. Select your Recall method.
    Given the high probability that it could fail, it might be best to recall it with a replacement message even when you did not want to send a message in the first place. This could be that apology message mentioned earlier so you don’t have to send yet another message.

    Recall This Message dialog box.

  4. Press OK to send the recall message and keep your fingers crossed that it will actually work.
  5. Tracking buttonWhen you had the option “Tell me if recall succeeds or fails for each recipient” enabled, you’ll receive notifications once the recall message got processed by the recipient. Once you have received it (or the first one in the case of multiple recipients), you’ll also see a tracking icon for your original sent item. Open this sent items again via a double click and click on the Tracking button to see an overview of the recall results.

Note 1: The recall could still get reported as a success even though the recipient has read the original message but did not mark it as read. It’s best to see this feature as a workflow rather than a failsafe.

Note 2: When you had sent the message to multiple recipients, the recall message will be sent to all recipients as well. You can’t recall the message for only 1 or a select few recipients of that message; It’s all or nothing.
