Can't reconfigure Thunderbird to receive or send.
Hi, Last week, my Thunderbird just stopped showing new incoming mail. I have tried many, many times to get it up and running with my new emails. I am with Telstra as my internet provider, running Windows 11 and Norton360. I am not able to send either. All my folders are OK, and I have not lost any content. I am able to see new emails on my Telstra email but I prefer to have Thunderbird. Please advise what to do. Ryan

Almost certainly Norton is the culprit, trying to intercept your secure connection to the server.
These are some generic suggestions to avoid problems with anti-virus software.
Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-to-find-your-profile
Don't let your anti-virus software scan incoming and outgoing messages.
Don't let your anti-virus software scan attachments.
Don't let your anti-virus software intercept your secure connection to the server.
Remove any add-ons your anti-virus software may have installed in Thunderbird.
Keep it working. http://kb.mozillazine.org/Keep_it_working_-_Thunderbird
And last but not least, backup your Thunderbird profile on a regular basis. https://support.mozilla.org/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile
