Windows 10: outlook express unable to send emails they get stuck in outbox

outlook express unable to send emails they get stuck in outbox

Unknown message stuck in Outlook 2016 outbox

The last two days I've noticed when I start Outlook (I have Office 365) it tries to send a message but fails and error code 0x800CCC0F is generated (see screen shots). If I send an e-mail, the e-mail is sent but whatever is stuck also tries to send. Not sure how to correct this. I've run scans with Malwarebytes and Windows Defender and nothing shows up.

Here are some screenshots.

 

Emails keep getting stuck in Outbox


Every time I either reply, forward or send an email, it gets stuck in the Outbox and I cannot send it.

 

why are my emails stuck in the outbox?
