Try to start Windows 10 in safe mode with networking enabled.

Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.

This did not do anything for sending emails except mess my text size up on everything. Now everything is too small. :(

As a first step, I would create a whole new server (settings) like server.rr.number2 and act like it's all a brand new acct, set it up from scratch. make sure your anti-virus, firewall is disabled, or you know how to set up the firewall. Do you use a vpn? that can be a problem for outgoing emails. second step would be to remove the new version software and reinstall the older versiion pointing to your existing data directory. also, reboot windows into normal mode if you have not already. small text is a know issue

This did not do anything for sending emails

So what exactly happened when you did attempt to send a message in Windows safe mode?

The same message- it times out about trying for a minute or 2 and gives me the times out message "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.brighthouse.com timed out. Try again."

"I wish it never updated. I do NOT like the new format."

Then why don't you uninstall and reinstall the previous version. This guy christ1 could take weeks trying to fix you...

Attn: christ1, you know if mozilla would work more to make all around useful software instead of trying to change the view every other update, people might stick with it.

Why not make a fallback solution? that way people can revert back to their previous software ver without fear or loss of data?

Why not make separate security updates? That way people can remain safe without having this month's horrendous theme forced on them.

Why not make useable backups? I tried seamonkey and it wouldn't import PW and links... RIGHT?

Does anyone know a way to reinstall the older version?

 Security Software

   Type: Name

     Antivirus: Norton 360
     Antispyware:
     Firewall: Norton 360

As per your Troubleshooting Information there are two brighthouse.com accounts. Do both have the problem?

Antivirus: Norton 360

I'd still think Norton is playing a role in this. 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

It is not the Norton 360. Gmail works just fine. Both spectrum account do not work. This all started with the new update. There is a problem with the new update. How can I roll it back to a prior update?

I do not have %AppData%\Thunderbird\
