What are you talking about. You appear to me using the new account wizard as some sort of defacto account manager is what I am getting from your description.

The account manager. On the toolbar > Hover over the "Options entry in the menu and select account settings.

Hey Matt. Thanks for replying. Sorry if I wasn't clear. I am using the Tools>Account Settings menu in Tbird. Not my first rodeo. I have 10 email addresses I manage and am trying to consolidate as well as move mail from some very old Earthlink/Springmail/Netcom accounts to my domain accounts. The problem is two-fold. When navigating TBirds Account Settings menu, I can select one of the emails settings selections, say email1@yoohoo.com's server settings. when I go to select the copies and folders menu or navigate to email2@yohoho.com, nothing on the right panel of the menu changes. It's still showing the server settings for email1. Capisce? This issue became noticeable as I was trying to add new emails from my domain setting them up as Imap. Until now I have only set up emails as POP. The settings I am using are valid, as verified by successfully adding the imap email to my tablet. When attempting to add the new email as imap, it sticks at checking password or alerts me that the incoming server already exists. I have tried turning off proxy, firewall and antivirus. I am able to add the new address using POP settings just fine.

I solved the navigation issue by uninstalling and reinstalling Tbird. Still can't add imap emails though.

I would have tried safe mode (holding shift while Thunderbird starts) as it sounds like either an add-on or something that safe mode mght have "miraculously" fixed.

However. I digress from your last post. If they are ancient domains and services, do they actually offer IMAP? Looks like Mindspring do https://support.earthlink.net/articles/email/imap-email.php

Who is your host?

Check you account settings. Do you have and account there (or in outgoing server (SMTP) that will have a duplicated name if you add the next account. I think you might find the issue is in outgoing server.

My recent experience with adding a new account using a Dell laptop with Norton's fine product on it. Basically I had to turn Norton's off or it scrambled the account setup process. Everything failed. Perhaps your anti virus needs a short holiday as well while you set up the account.

Matt, I am getting rid of the old addresses. My ISP is 1and 1. As I said above, the IMAP seetings work just fine on my tablet. And I tried by shutting off my AV and firewall. And put Tbird in safe mode turning off all extensions. The incoming server error is random, mostly it just hangs on checking password. I've also tried all the different ports, adding those ports to port forwarding on my router. Guess I'll just stick with POP. Thanks for trying.

Are you doing it like this:

• Menu icon > New Messages > Existing mail account
• Enter name
• enter email address
• Enter password
• click on 'Continue' button

Thunderbird attempts to locate settings.

• Check..has IMAP been selected?
• click on 'Manual config' button.

• Make sure IMAP is selected.

Check settings

• Incoming Server: imap.1and1.co.uk
• Port: 993
• Connection security: SSL/TLS
• Authentication Method: Normal Password
• User Name: Full email address

• Outgoing Server (SMTP): auth.smtp.1and1.co.uk
• Port: 587
• Connection security: STARTTLS
• Authentication Method: Normal Password
• User Name: Full email address

Pretty much the same, except not the uk address and my smtp server doesn't ask for the auth part. I tried that just for the heck of it and Tbird can't find that server.
