Hi Robert, Thank you for reaching out to this forum. I'm Utkarsh and as a fellow Microsoft user, I'm here and ready to help you today. I am a user like you, this is a user forum and not Microsoft directly. For me to better understand the issue, I’d like to ask a few questions: 1. What is the type of account you are using? Is it an MN3656 work/school account or a Microsoft/personal account 2. Is this happening to all emails or to specific senders? Here are some general troubleshooting steps you can try in the meantime: 1. Check SMTP Server Settings: Verify that the SMTP server settings for your outgoing mail server (SMTP) are correct. Ensure that the server address, port number, encryption method (SSL/TLS), and authentication details are accurate. 2. Update Outlook: Ensure that your Outlook application is up to date. Updates often include bug fixes and improvements that can resolve such errors. 3. Restart Outlook: Close and reopen Outlook to refresh the application and potentially resolve any temporary glitches causing the error. 4. Re-add your TWC Account in Outlook: If the above steps don't work, try removing and re-adding your TWC account in your Outlook application. This can sometimes refresh the connection and resolve configuration issues. I am NOT a Microsoft Agent/Employee. I hope this is helpful! Best Regards, Utkarsh

This just started this morning, so I suspect that it is because of a change by you..
