Outlook is not sending email

Having emails stuck in Outbox is a pretty common issue in Outlook: you’ve wrote an email, clicked to send it, but it stays in the Outbox folder and Outlook is not sending the email, no matter what you do. This article details possible causes & solutions and it applies to all Outlook versions, including Outlook 2013.


There can be many reasons why Outlook wouldn’t send an email. To narrow the cause of the Outbox stuck emails, first of all you should check if you receive an error message while you perform a Send / Receive operation.

If you receive an error message while you try to send the email

Most likely there is a communication problem between Outlook and your outgoing mail server, so the email is stuck in Outbox because Outlook can’t connect to your mail server to send it.

If you do not receive an error message while you try to send the email

The problem is likely to be related to your local Outlook configuration.

If Outlook is not sending only some Outbox emails, make sure you don’t have the habit to preview / open / click on Outbox emails: your Outbox emails should be unread (marked with bold & italic) otherwise Outlook will not send the email and it will be stuck in your Outbox folder. Check your Outbox emails:


— if the email is bold and italic, then it is ready to be sent;
— if the email is just marked with bold, then it was read;
— if the email is not marked with bold or italic, then the email was read and edited. As in the following screenshot, only the first email (with the subject “Unread email”) is going to be sent by Outlook while the other emails will stay in the Outbox folder:
