For anti-virus & firewall software I use the following: ZoneAlarm Extreme Security version: 15.1.501.17249 Turning ZA off made no difference.

Thunderbird does work in safe mode but still was not able to send my messages.

Not sure if this will help, but I'd advise using the aol smtp server to send from the aol account (smtp.aol.com on port 465, SSL/TLS, normal password, User name = address part before the @) and to send from the hotmail account on smtp.office365.com, port 587, STARTTLS, normal password, User name = your hotmail address. I think your gmail account will also not send through the outlook.com smtp server.

Originally I was using smtp.aol.com and had to switch. As you suggested, I tried it again on port 465, SSL/TLS has remained always. Attached is the error message it was and again getting. It times out!

You cannot mix and match these. Use each provider's own smtp server; aol with aol, outlook with outlook, gmail with gmail.

Account 1 (and incidentally 2) are OK. All the others use someone else's smtp. Not good.

Thunderbird used to work very well. The solution is to use a different mail app and that is what I intend to do. I see that I am not the only one with unsolvable problems. I will be deleting Thunderbird from my computer. Thanks!
