Easy way to delete outbox messages in outlook.

I have a lot of unsent messages in my outbox folder in outlook. It failed to send because of too large attachment or my email server is down when doing so. I want to clean the messages in my outbox that is not needed so I really want to delete it.

When I click the delete button, it does not work the messages is still there. Sometimes outlook gives back this message "outlook has begun transmitting this message" so you are unable to delete it. Sometimes no response, just you can't delete.

To easily delete outbox message

1. Open your outlook and set it to work offline. (To stop outlook from trying to send all email messages)
• In Outlook 2010, 2013 and 2016, go to the Send/Receive ribbon tab > Preferences group and click "Work Offline".
• In Outlook 2007, 2003 and lower, click File select Work Offline
2. Close your outlook then open it again.
3. Go to your outbox then you can now delete your stuck messages. Or move your outbox messages to your draft folder if you need to reuse the message.
4. Then reset your outlook to work online by following the step number 1, just unselect the work offline button to get back to online mode.

If your outlook is already transmitting the messages. Just cancel the send/receive then follow the Step 1 to 4. If still can delete it start your outlook in safe mode then try to delete again.
