Click Send/Receive > Work Offline.
The Work Offline button in Outlook 2013
In the Navigation Pane, click Outbox.
From here, you can:
Delete the message. Just select it and press Delete.
Drag the message to your drafts folder, double-click to open the message, delete the attachment (click it and press Delete).
If an error tells you Outlook is trying to transmit the message, close Outlook. It may take a few moments to exit.
After Outlook closes, start it again and repeat steps 2-3.
After you remove the attachment, click Send/Receive > Work Offline to deselect the button and resume working online.
