I have been using THUNDERBIRD for more than 10 years, changed and installed into many desktops and laptops. But this time, after I installed in my new desktop WIN8, I cannot set up any of my IMAP accounts. They are not gmail/yahoo. They are my business emails. But the settings I have been using is the same and not changed, tried uninstall, reinstall, I'm copying the exact settings that I have on my laptop (which is working perfectly fine). It kept saying "username or password is wrong"!!! My username is the full email address which I put it correctly. The port is the same port I used on the other computers. I just don't understand why is this happening...my laptop is using WIN8 as well...

I can install and use with MAILBIRD, so the setting are all correct. But I just can't set any of my 5 accounts (same domain) up on this THUNDERBIRD this time...it's really frustrating.

Can anyone help please??? 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...
