With message recall, a message that you sent is retrieved from the mailboxes of the recipients who haven’t yet opened it. For example, if you forgot to include an attachment, you can try to retract the message, and then send a replacement message that has the attachment. Message recall is available if both you and the recipient have an Office 365 or Microsoft Exchange email account in the same organization.
Recall an email message:
Note: Recalling a message can take up to two minutes to process and will only be successful if the following conditions are met:
1. The recipient uses the Outlook client (not Outlook on the web or the Outlook app), and Outlook is running.
2. The recipient is on the same Exchange server (a Oryon employee). It will not work if the message was sent to someone outside of the Oryon.
3. The message must still be unread and in the recipient’s Inbox.

Step 2. Double-click the message that you want to recall.
Step 3: On the Message tab, in the Move group, click Actions, and then click Recall This Message.
