Accessing the Sent Thru Folder

All Thru emails that you have sent are kept in the Sent Items folder that is native to Outlook. This will store the message that you have typed into the regular mail window.

  1. From the Outlook toolbar, click Thru Explorer. The Thru Explorer window displays.


  2. Click on the Sent Thru folder in the left tree view to display all Thru emails.

Immediately Expiring a Thru Email

You can immediately expire a Thru email if you wish to prevent further downloads of the files you have sent or the private message you have written from the Sent Thru folder in Thru Explorer.

  1. Select the Thru email you wish to expire and then click Modify.
    In the Edit Thru message window that opens, click Now.

Removing Recipients from a Sent Thru Email

One can remove the recipient to a Thru email after delivery. If you remove a recipient from the Thru email, however, they will be prohibited from downloading any further. If they have already downloaded their files they just will not be able to download them again.

  • You can only remove recipients if you have more than one recipient to whom you have already sent mail.
  • Note: Once the email has been sent, you cannot add more recipients to it; they can only be removed. If you wish to add other recipients, you must create a new Thru Email.

To remove recipients:

  1. Navigate to the Sent Thru folder within Thru Explorer.


  2. Click the Thru email you wish to edit and then click Modify.
    Or, right-click on the Thru email you wish to edit and select Open.


  3. The Edit Thru message window opens.
  4. Right-click on the email address you wish to remove and select Remove from the drop-down menu.
