Since about a week ago, I've been unable to send messages through Thunderbird on my Windows 10 PC. I keep getting the error message shown in my first attached screenshot. I have updated to the latest version (102.1.2 64-Bit), although this was happening during the previous version. The second attachment is a screenshot containing the settings I've been using that had previous worked. I've tried several different solutions, including the following:

- Created a new app-generated password and applied to the incoming IMAP and outgoing SMTP - Adding this Thunderbird version to the list of firewall exceptions - Paused my antivirus (via Surfshark VPN) to send a test email (didn't work) - Alternated the Connection Security between "STARTTLS" and "SSL/TLS" - Tried using the default port for STARTLS (587) with SSL/TLS (and vice versa with default port 465 in STARTTLS)

I'm basically at a loss at this point. Any suggestions on what the underlying cause could be and/or solutions? My ISP is Spectrum, in case that helps.

Somehow, this issue resolved itself. As I was sending another test email, it prompted me to re-enter my new app-generated password, then the email went through. So I guess updating the password fixed it, and there was just a delay in getting it to allow me to enter my new password? Very strange, but whatever

Hi snoopy15, great it's working now! I also found that Tbird (throught several versions) had trouble with icloud in particular, with subscribed folders missing etc. I just tried sending from my icloud address and it worked. The only difference ins outgoing server (SMTP) settings to your screenshot setup is that I don't have the "@icloud.com" behind my username. Maybe something to try next time you run into trouble. ;)
