I am unable to send emails from my Thunderbird client. This email is hosted through Microsoft 365 (using GoDaddy as a provider). If I log in through the Office 365 Webmail Client, I am '''able''' to send a test message to my personal email address and it goes through. This leads me to believe it is strictly a Thunderbird issue. I contacted GoDaddy support and they confirmed that everything is working correctly on their end. I have attached screenshots of my SMTP settings as well as the error I receive when I try to send an email. The password I use is the same password that lets me login to the Webmail client using Office 365. I am not sure what is wrong. I have another email address through GoDaddy that uses Microsoft 365 as well and everything works correctly, including sending emails. I have tried cross referencing my settings between the two and everything seems to be in order. I even reset my SMTP password in Office 365 AND in Thunderbird's password manager. Thank you for your time.
