Thunderbird suddenly having problem connecting to my email accounts
I've been using Thunderbird since at least v1 and never had an issue connecting to my email accounts. Suddenly today, I cannot get Thunderbird to connect to any of my accounts. To work through the most obvious items: - I'm running version 45.4.0. - My email accounts are all on my own domain. Nothing has changed regarding how to connect. - I have multiple accounts on multiple domains, and none of them can connect. - The issue appears to be in the authentication, not in connecting. I am judging this on the basis that I tried to set up a new test account to see what would happen. After creating the account, I tried setting this up as a new account in Thunderbird. I first let Thunderbird auto-configure the account. It identifies the "configuration found at email provider", but it is then unable to verify the password. I'm getting this on every account, including the new one set up to test this out. I tried manually configuring the new account, but encounter the same issue regardless of how I configure it. I have also turned off firewall and anti-virus to eliminate them as culprits. I should also note that my phone is configured for a couple of my primary email accounts that are not working in Thunderbird, but are working fine on my phone. I'm stuck on how to resolve this. Please help.

Who is your email provider?
I have email configured through my own domain server.
If the 'New Account' wizard fails to detect the correct server settings use 'Manual Configuration'. https://support.mozilla.org/kb/manual-account-configuration
As I mentioned in my original post, I've tried manually configuring it, in every way conceivable. It is something I've done hundreds of times and never had a problem, until now. The only thing I haven't tried yet is switching to another email client. It is starting to look like that needs to be the next step, which really is a shame.

This is a pretty silly approach IMV. Use the exact settings as per your email provider information. It's their server, and they know what the required settings are. I suppose they do have a support web site where you can look up those server settings, or alternatively ask their support. With the trial and error approach you're just wasting your time.
So, just to recap, my emails were all working fine for the last 15+ years until this morning. The only reason I've tried to configure an email account today is because the many others that all worked yesterday do not work today. They are fine when I access them via my phone's email client, but not fine when I try to access them via Thunderbird. In the interest of trying to determine why Thunderbird cannot access my email accounts, I tried setting up one new account, first via auto-config, then via various manual configs. Auto config did not work, nor did the manual configs. All email accounts, including, and especially, the many that worked fine for many years, experience the same issue the new one does, which is the authentication of the password fails. Of course, the password hasn't changed on any of them, which I can be sure of because my phone is accessing them fine, and I can log into them via my Cpanel. Note I said Cpanel, because there is no other email provider. I administrate the emails accounts myself. In conclusion, if I can log in to these accounts via Cpanel, and via my phone's email client, but Thunderbird fails, the only logical conclusion is there is an issue with Thunderbird. However, in reaching out to you to try to get some insight on the issue, I received no feedback worth anything. Instead, you selectively respond to one part of the overall explanation of how I've tried to diagnose the issue. If I've wasted any time today, it was in trying to elicit worthwhile information from this support board.

I disagree. Logging in via Cpanel and via your phone may use a different authentication method than using Thunderbird. If you haven't changed anything in Thunderbird and login suddenly fails, then there is a possibility something has changed on the server. Did you talk to your email provider about the required settings as suggested previously?
