It sounds like you have Thunderbird running on another computer and want the same setting on laptop. To assist you, we need to see settings on old and on new. There is likely a small error you are doing in setting up the second one. But here's a tip: When setting up a new account, do NOT enter password. Let Thunderbird confirm the connection first. Once done, then enter the password. Doing the setup that way has solved many similar problems. And if you prefer IMAP, then keep it. Switching to POP will only cause future problems in that the two computers will not be in sync. Try my tip and then report back.

Hi David!!!! oh my gosh, I just found this reply, thank-you!! yes that is exactly what I want to do. I'm sorry I just posted another question, I saw the My question link & found your response. Thank-you I will try this right now. Bless you!! Sandy

Hello David, I'm back. I'm sorry it didn't work. I left out the pw and the configuration was found, I entered the pw and got the same note about unable to log in at server, etc... Is there something we could try to fix it? Your help is greatly appreciated!! Sandy

I'm sorry, an additional question, I created a pw on this Mozilla questions page, does this new pw change the password on my Thunderbird e-mail account? Thought I'd better make sure on that.  :)

Hello, Sandy, The web password for the forum is just for the forum. Nothing to worry about. Can you post a screenshot of your server setup?
