Running windows 11 in S mode, Spectrum email. I had been using Outlook but on 11 February, it stopped working. Wouldn't send nor receive. Webmail works fine. Downloaded Thunderbird. Set up my account and started receiving emails. Went to send an email, and it failed to send. Checked all settings and they match Spectrum's server settings.

Trying to troubleshoot, but struggled with directions on the internet. Tried to load developer tools and nothing happened. Found I could open the error console with keypad. The error console says "Could not start Browser Toolbox, you need to enable it." Could not find out how to enable it.

When I attempt to send email, three messages show up in the error console. "NetworkTimeoutError: a Network error occurred SmtpClient.sys.mjs:476:17" "SecurityError info: SmtpClient.sys.mjs:492:21" Note, no error text was displayed. "Sending failed: ... server (SMTP) timed out.... MessageSend.sys.mjs:341:32"

When I first started running Thunderbird, I remember a certificate error with the Spectrum certificate. I enabled an exception and was able to receive email. Thinking this might be related to the security error on receiving, I wanted to remove the certificate exception so I could see the reason for the security error on receiving. Comments say it is stored in the profile. If I try to open the profile, Thunderbird says profile not found. I found the profiles, but the path to them is not the path listed under Troubleshooting Information\About Profiles.

My primary issue is not being able to send emails. I would also like to know how to remove the certificate exception.
