Make sure Thunderbird isn't blocked by a personal firewall.

I checked my Windows firewall and Tbird was not on the allowed list so I added it, allowed it and I still have the same problem.

The Windows firewall allows outgoing connections by default. The question was more about any personal firewall you may have installed. That would include a firewall as part of an anti-virus/security suite software.

I have Avast home, it has never given me a problem. I turned off the Avast protection for my email and Tbird still won't download emails. I must add that I can send emails but Tbird cannot save tell email in its archive.

I have used Tbird with yahoo for about two years and no problems. Now, starting about 2 weeks ago, I can't access yahoo emails through Tbird. After searching for an answer I have learned through yahoo that you must use POP instead of IMAP with Tbird and of course, they charge a fee for that to get the correct settings through yahoo plus. Has anyone else run into this ?

Evonlee,

Try to start *Windows* in safe mode with networking enabled.

- Win8 http://windows.microsoft.com/en-US/windows-8/windows-startup-settings-including-safe-mode

- Win7 http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode

- XP http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx

Still in Windows safe mode, start Thunderbird in safe mode.

Does the problem go away?

SFmedic,

Please raise your own thread for your problem. Your statement about Yahoo is not correct.
