I have been using THUNDERBIRD for more than 10 years and never had this problem! I have installed on many different desktops, laptops and macs, and had no problem. And this time when I tried to set up email accounts on this new computer, it just keeps saying "username or password is wrong"...I have 5 email business emails account (with the same domain), hosted by Network Solutions, all are working fine on my laptop and other computers. I copied word to word, number to number of the same settings, nothing is not correct. It just keeps saying wrong username and password. I have no idea where the problem is!! I never had this problem, I tried uninstall, reinstall, didn't help.

I can install and set up my accounts on MAILBIRD, and it's working. So there is nothing wrong with the servers...should be Thunderbird hidden settings or something. I dont' know.

Can some expert help please? I'm living on Thunderbird...I have been using it for more than 10 years and I'm addicted to it....please help!!!!

Thanks in advance!!!

I interesting note:

MAILBIRD uses port 993 for incoming mail but THUNDERBIRD uses port 143

When uses 143, it kept " checking capabilities...." then I changed to port 993 (like in MAILBIRD), it said "connected to.....mail," but then "timed out"

Any idea please???? help....extremely frustrated...

Does that mean I have to abandon this Thunderbird from now on??

try disabling your anti virus while you configure your account. Many anti virus program mess up the process.

I am having the same problem and disabling my anti-virus software did not help.
