Thunderbird downloading all unread messages again
I have been using Thunderbird for many years. One of my accounts is IMAP and set to leave messages on server until I delete them in Thunderbird. As a result, I have more than 3000 unread messages in my inbox.
Suddenly today, without making any configuration changes, Thunderbird is downloading all unread messages again, duplicating what is in the Inbox folder.
I am using version 52.6.0 and it says that it is up to date. What happened?

Seriously, I doubt you are using imap. THe option to leave messages on the server until I delete them is not available on IMAP accounts.
So please add the troubleshooting information to your post that we might confirm which it is IMAP or POP among other things.
To find the Troubleshooting information:
- Open Help (or click on three-line-icon and select Help)
- Choose Troubleshooting Information
- Use the button Copy to clipboard to select all. Do not check box "Include account names"!
- Paste this in your post.
I did as you requested. You are right, it was pop3, not IMAP as I initially thought.

It is account 1 that is having this problem. Most of the other accounts are inactive or essentially dormant. The file was too large to post intact. I deleted only the text that had to do with printer info for PDFCreator.

It is only rarely that the text after the account settings and extentions is of any use.
Now to your mail problem. Basically it will be an issue between the fundamental process used to work out which mail is downloaded and the cavalier way ISP's manage their mail systems these days.
When Thunderbird downloads mail and is instructed to leave messages on the server, it writes a log of what is what in a text file called popstate.dat. This file contains the reference number used by the server to describe the actual email.
This process works a treat, as long as the server operators respect the importance of these reference numbers. I am seeing more and more instances of providers not respecting that and re-indexing the mail on the server. To install new hardware or software or as some sort of maintenance I do not know. But it must also be remembered that when the POP protocol first appeared in the last millennium that having more that a couple of hundred emails in an account was bad form and would see you run out of space to store new incoming mail.
So what happens is the server re-indexes the mail, and all of the until I delete it and where and what was the last email stuff just goes up in virtual smoke. Thunderbird is forced to start getting your mail as it is it a new account as what it has stored is useless. The result is you get lots and lots of duplicates.
I think it may be germane that Verizon has migrated their email base to AOL.. That migration may have seen a re-index of mail. https://help.aol.com/articles/verizon-move-to-aol-mail-updating-your-third-party-email-program-or-mobile-device-with-your-new-account-information-pop3
