In the Outbox, a message can linger and perpetually fail to send—until you remove it. Deleting an email stuck in the Windows Live Mail Outbox is easy.
Delete Emails Stuck in the Windows Live Mail Outbox
To remove a message from the Outbox folder in Windows Live Mail when it persistently fails to send:
Select Work offline in the Tools group of the Home tab. Select the View tab and choose Compact view if it is highlighted. Select Mail at the bottom of the folder list. Select Outbox in the list to open the Outbox. Select the message you want to delete and keep the mouse button pressed. Holding down the Ctrl key, drag the message to the Drafts folder for an account or Storage folders. Release the mouse button over Drafts, then release the Ctrl key. Highlight the message you want to delete in the Outbox folder. Press Delete. You can also press Ctrl+D or select Delete in the Delete group of the Home tab. In the Drafts folder to which you copied the message that failed to send, double-click that email to edit it, fix any problems, and attempt delivery again.
Press Delete.
