I have an account that normally works with my Outlook 360 account. All of a sudden I started getting the attached error message whenever I try to send an email.

What is causing this and what can I do to fix it?
Regards

Check the ports you are using under Advanced Account settings. You probably need 995/SSL for incoming mail and 465 or 587/SSL or TLS for outgoing mail.
Make sure under Outgoing Server that you have authenticated properly. This affects sending and that is where you have an issue.
Looking at the picture, did you select (check) Save Password.

Also you can use special tools...
For example: Outlook Fix Toolbox
