If a message gets stuck in your Outbox, it could be due to a large attachment.


  1. Go to Send/Receive > Work Offline
  2. In the Navigation Pane on the left, select Outbox.
  3. Now you can:
    • Delete the message by selecting and pressing the Delete button.
    • Drag the message to the drafts folder, then open the message by double-clicking it, and delete the attachment (pressing Delete upon selection).
    • Place the attachment on a file server or any other location where others can access it, and then add the location to the message.
  4. In case an error says that Outlook is trying to transmit the message, close Outlook, and it may take few moments to exit.

Note: In case Outlook doesn't close even after several minutes or an Outlook is not responding message comes up, press Ctrl+Alt+Delete and select Start Task Manager. In the Task Manager, choose the Processes tab, find and select outlook.exe, and click on End Process.


  1. When Outlook closes, restart it and go through steps 2-3 again.
  2. After removing the attachment, go to Send/Receive > Work Offline in order to deselect the button and continue working online.

Note:  Messages can also get stuck if you click Send when you're not connected. Click on Send/Receive and observe the Work Offline button. In case the button is blue, click on it to connect (the button will turn white), and then click on Send All.
