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.

I assume you have two outgoing smtp servers, one for each email address.

The first image shows you using Office365 (Microsoft) -smtp.office365.com (default) But is that the same one as you show in the second image ?

In second image - edit the 'Description' type an A before the 'Office365' and click on OK then look at the account as shown in first image - does it now show AOffice365 ? If no then you are using the wrong smtp server, click on drop down and reselect the correct one that starts with AOffice

Click on OK

Restart Thunderbird.
