What is happening? Thunderbird users have been experiencing some issues with Exchange as we migrate to the new Exchange 2016 infrastructure.
One error is an ongoing pop-up for a Command Error 12.

What do you need to do? The solutions from the Thunderbird discussion board is:

Re: Command error. 12

Tools > Options > Advanced > General tab or Menu icon > Options > Options > Advanced > General tab
click on 'config editor' button. it will tell you to be careful Smiley Happy
In top search type: send_client look for this line: mail.server.default.send_client_info; Value = true
Double click on that line to toggle TRUE to FALSE It will stop Thunderbird from sending the "ID command". the error seems to be happening with some servers that claim to support that command but return an error when it is used.

Close window - top right X click on OK Restart Thunderbird.
