This error continues to occur at random intervals on various accounts of mine. These are located on an IMAP server through my local ISP. I have confirmed many times over that there is not a problem at the ISP. I can even log in on another account on my local PC and run that instance of T'bird and access the account that fails on the other local PC account. This has happened over a number of revisions of T'Bird, and on multiple different T'bird installations on various computers. It is nearly 100% certain it is a T'bird bug.

I have tried adjusting some of the advanced IMAP account setting in T'bird, but it has had no noticeable effect.

The only solution I have found is to rename the old account with a fake log-in, and create a new account. This has always fixed the issue, but it is a time consuming pain, and seems like it could be isolated and repaired without too much effort.

If anyone has any insight to the problem source that may be of benefit to me and others, let us know.

How reliable is your Internet connection? Do you use a dodgy DNS server? You may try a different one.

Does this happen when receiving mail, or sending, or for both?

How often do you check for new mail?

What is your anti-virus software?

What is the size of your mail files?

I can even log in on another account on my local PC and run that instance of T'bird and access the account that fails on the other local PC account.

Are you saying you do have two computers, both run Thunderbird, both they have same accounts set up, and all accounts are configured identically?

This has happened over a number of revisions of T'Bird, and on multiple different T'bird installations on various computers.

So it's not limited to one particular computer?

It is nearly 100% certain it is a T'bird bug.

If you're certain it's a bug you can raise a bug on Bugzilla. You should include something substantial to back your claim, e.g. like logs. https://bugzilla.mozilla.org/

What settings? Did you make these adjustments on all affected computers for all affected accounts?
