I am ready to compose a new message. I address the message to a group and since I want the response to go to a different person, I enter the person's email in "Reply To" option. Thunderbird won't let me send the message. I have used the feature in the past for years. Is there is a fix to the problem?

Thanks in advance.

It's not a TB issue, as some mail providers may allow non-registered Reply-to addresses, and some may not.

What error message do you receive when Thunderbird refuses to send the message?

It gives me the following error message. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please check the message and try again.

This problem came up some time ago with AT&T accounts. The issue was that the Reply-to address wasn't an AT&T account already in TB or designated as an 'authorized' address in the sending account's webmail settings. This makes sense, that you can't specify a Reply-to address that you don't 'own'.

If you can't add the account in the Reply-to field, add a line in the message body such as 'Please direct all replies to abcd@example.org'.

Thanks; at least I now know what the issue is. I suppose i just have to live with it. Ideally, TB design team should fix the problem.
