How do I resolve outlook emails stuck in outbox?

[woakeschris]

I am using MS outlook email account for the effective emailing communication. I have decided to use MS outlook email for various emailing purposes. MS outlook email has many unique and amazing features, so I select this email service for my official task. I am experiencing Outlook Emails Stuck in Outbox. This is a very common error experienced by many users. My email sending procedure takes a lot of time and message gets trapped in outbox. I don’t have skills to find out many reasons of this error.

When a message gets stuck in your Outbox, the most likely cause is a large attachment.

Click Send/Receive > Work Offline.
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, and 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.
