I got a new HP laptop with the Windows 11 operating system 2 weeks ago, downloaded and set up T-bird. I am able to receive emails but cannot send them. I have worked with my ISP to be sure that I have the correct settings for the SMTP server and it still will not complete the sending process. They say that the problem is not theirs as I have the proper settings, receive emails and can send and receive emails with their webmail client. When sending there is an exceptionally long time with the sending progress window showing activity and then I get a Sending message failed pop up. I first loaded the then current version of T-Bird on the new laptop and then reloaded it several days later to no avail. Today I downloaded the new version of T-Bird 102.0 hoping for a resolution, but no success. What do I need to do to get full functionality from T-Bird?
