Send button in Thunderbird won't work in write mode, but will work in reply mode

RichV

The send function is inoperative (gray color) when I am originating an e-mail, but is functional (black) when replying. Uninstalling antivirus or changing from Bitdefender to Norton doesn't fix the problem. I uninstalled Thunderbird and reinstalled. The send function worked with a new e-mail. But once I restored my profile, the problem returned. Using a 4 year old profile still produced the problem.

what is showing in the "from" address when you click write?

my name and e-mail address shows in the "from" address

And what is showing in the "To" address? The Send button is greyed out until one or more recipients are specified, which happens automatically when you reply to a message…

The e-mail address that I have entered in order to send it to that recipient.

I have the same problem with a grey send button not working. If I save to draft and then open the email it will send. This problem happened a little while ago and then seemed to clear, but has now come back. I use a Mac, with latest updates. Hopefully a non too technical solution can be found..
