For the past few days, since the Thunderbird update, I have been unable to send any emails from my thunderbird account. I have also tried going into my juno account online, and any emails that I send out come back with the mailer demon response - tha the email did not go through. With help from Juno I have tried to reconfigure my account, turn off my Anti-Virus and Firewall (Norton 360) changed my password many times, but nothing is working.

This is the error message that I receive...An error occurred while sending mail. The mail server responded: Access denied...4664b9656464c9c921b121b9b9c5354d11b420a93520358d357984a56d99d1cd24a07174e57559e0b1f00c7149f025b925ed4d45140c20f5.... Please check the message and try again.

In the past, I have received this message and was told by Juno to change my password. When I did that, I was again able to send out emails. But this time nothing has worked. I even tried a system restore to go back before the Thunderbird update, but that did not help either. I really need to use my email, and just can't imagine what has happened to it. I am not sure if this is a problem for Thunderbird or for Juno my email server. Please advise. thanks.

To diagnose problems with Thunderbird, try the following:

  • Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
  • Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 8, Windows 7, Windows Vista, Windows XP, OSX
If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.

Note that Norton's is notorious for not being "off" when their interface says they are. Safe mode with networking guarantees that.
