Thank you for your question, my name is ***** ***** I look forward to assisting you.
Please note, click on Reply to Expert to reply to me, a rating is only needed when we are finished.
It means they are blocking you from sending.
First step, go to
Sign into your account there and then send an email there as a test.
Then go back to Thunderbird and let me know if you can then send please.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Let me know the results please
