Use Delete to retract a sent item from the recipient’s Mailbox. You can retract a mail or phone message from those recipients who haven’t yet opened the item. You can retract an appointment, reminder note, or task at any time. Items that have been sent through the Internet to other email systems cannot be retracted. Furthermore, items that have been configured to be delivered at a future time through the Internet (as described in Delaying Delivery of an Item) cannot be retracted.
Click the Sent Items folder in the Nav Bar.
Right-click the item you want to retract, and then click Delete.
If you click Delete and Empty, items are deleted and purged, and they cannot be recovered.
Select the appropriate option.
My Caching and Online Mailbox: Deletes the item from your caching and online mailbox.
My Caching Mailbox: Deletes the item from your caching mailbox.
Recipient’s Mailbox: Deletes the item from the mailbox of all recipients. If you clicked Delete in Step 2, the item is not deleted from your mailbox. If you clicked Delete and Empty in Step 2, the item is also deleted from your mailbox.
All Mailboxes: Deletes the item from your mailbox and the mailbox of all recipients.
If you have selected to retract this item from other recipients’ mailboxes, you can type a comment to the recipients, explaining why the item was retracted.
Click OK.
To see which recipients have opened your message, right-click the item, and then click Properties. Email cannot be retracted if it has already been opened.
