How do I fix "Unrecognized command: ID"
I get this message for all operations. It does not seem to effect the operation of Thunderbird. I am using version 68.3.1
Chosen solution
So from the log I got.
2019-12-27 19:34:02.916000 UTC - [(null) 9352: Unnamed thread 1CC96040]: I/IMAP 1BC19000:mail.twc.com:NA:CreateNewLineFromSocket: * CAPABILITY IMAP4rev1 UIDPLUS NAMESPACE QUOTA SORT SORT=DISPLAY ID
The important part of that is that the server identifies itself as supporting the ID command.
So latter Thunderbird send such a command.

The TWC server responds.

That again is Unrecognized command: ID
So I have no doubt at all that the TWC server is not only the problem child, but that is it actually lying as it apparently does not support the ID command. Ironically theID command was created to make tracking issues to particular server/ Client software. It serves no purpose except for humans reading logs to identify the software being used.
Some years ago Thunderbird introduced user preferences to get around sub standard work with the mail server software used by charter (interMail). This was a follow up to bug 1231592 They appear to still be using the same product in production, I would expect nothing much has changed. It is identified in the log as
OK IMAP4 server (InterMail vM.9.01.00.037.1 201-2473-137-122-172)
Searching on Google shows an announcement from last century that IBM would be selling Software.com's Intermail But I can find no references to this software since the turn of the century. But it's sister openwave appears to be owned by Synchross they say
"Provides Operators the back-end framework for branded, white label email service that’s reliable, consistent, and safe with the potential to introduce and promote services that can be monetized."
I wonder how they monetize email?
But I digress, there is a global setting to suppress Thunderbird's use of the ID command. Use the config editor to set mail.server.default.send_client_info to false (right click the preference in the config editor to get the menu of actions. See Bug 741374 for the source of the pref. I have no idea where it started. )

Changing the IMAP Mail Server Port to 143 worked for me and fixed my problem. See the answer above from sfhowers. Thank you

Which Port was this for; Incoming/outgoing?
SOLVED!

Bibb, were you referring to Darylcady reply? If so, saying "solved" and not answering the question I gave means little... Did you use the same port 143 to correct the issue, and if so which server (incoming/outgoing)? Do elaborate, as I'm having the same issues with "...commmand: ID" and intermittent ability to send/receive email with and without VPN use... Thx...
I used what Matt provided in detail!
After changing the IMAPI to Port 143, I stopped getting the Command: ID error had trouble when I launched TB, and new mail did not come in. Changed input server IMAPI back to 993 and they all came in. Then changed back to 143 and mail started working again. A little confused.

Thank you for the update and responding. Did you happen to notice whether "working again" was after a TB update, or the same Version? Which version are you running? I'm on the latest ver 68.4.2 (32bit) though my system is a 64bit Win7. Hope to upgrade soon to a new system with Win10 64 bit, but am afraid of losing archives of TB email, even though I know about backing it up...
This thread has a solution, did you miss it or are you determined to just mess around for ever trying random things that will not work.
Changing ports will not work. Changing server names will not work. Making changes by the phase of the moon will not work Hoping for a software update from your mail provider might work, but it has not yet.
Or you could just modify the preference like I said back in December.
