I am getting errors when receiving some valid html messages that state 'Unknown property 'mso-table-xxxx '
I am getting a valid forwarded email in html format, but only see the html tags/text when in Thunderbird. Most html comes in fine, but when I receive an occasional mail sent from another Thunderbird user I get error messages stating 'Unknown property 'mso-margin-top-alt', or 'Unknown property 'mso-margin-top-alt', etc.

The mso in mso-whatever refers to Microsoft Office. Someone may have composed the message in Word and pasted into Thunderbird, or it may have been edited in Microsoft Outlook at some point.
That still doesn't explain why the message display is corrupted because most programs simply ignore tags/properties they can't understand. There probably is some other problem with the message that is causing the HTML portion of it not to be rendered normally.

The last similar source I saw the mailer was placing everything in the head section of the HTML
