I've run into security issue that is concerning me. I've been using the portable version, (portableapps.com), Thunderbird in windows. Everything is working fine. Can send\receive e-mails fine - no issues on multiple hotmail accounts! Everything was great. Yesterday I used my browser to log into one of my hotmail accounts and change the password. The next time I fired up Thunderbird... I noticed that I was still able to send\receive e-mails even though I had not updated my password for the hotmail account in Thunderbird! I verified the issue in MX Linux 19. This is very concerning. Should I not see an error in Thunderbird until I update the password?? That's what I would expect. An I missing something?? Please help.
