When importing mails from Outlook 2003 to TB, *some* (but not all) html messages
are mistakenly imported as plain text, and one can see the html code in the
message body area.

I found that if I change the message type from "content-type: plain/text" to
"content-type: plain/html" in the message store file, then everything works
fine. However, doing that by hand in a file that contains several thousand
messages would take days...

My Thunderbird build: version 0.9+ (20041117), zip version
Runs on: Windows XP SP2

Reproducible: Always
Steps to Reproduce:
1. Use the Import function from TB to import mails from Outlook 2003

Actual Results:  
Most HTML mails imported properly. However, some of them (especially some with
attachments) were imported with the wrong message type. They were wrongly
interpreted as "plain text" messages, with all the HTML code showing in the
message area.

Expected Results:  
The SW did not recognize that the messages were HTML messages. If I change the
message type from "content-type: plain/text" to "content-type: plain/html" in
the message store file, then everything works fine. However, doing that by hand
in a file that contains several thousand messages would take days...

Attachment: A zip file with two wrongly imported mails and the original headers in Outlook 2003

Two examples of the problem. They show the mails as they appear in the TB
storage after importing. In addition, the original "internet headers", as they
appear inside Outlook 2003.
As you can see, the contents were wrongly set as "Content-Type: text/plain;".
Perhaps the problem was that they were specified as "Content-Type:
multipart/related;" in Outlook 2003, which is not a frequently used
content-type...

OK, I will send it to you as an attachment, using the Outlook 2003 client. I
hope this is what you meant...

that should work - or I was thinking of the Outlook equivalent of Edit Message
as New, re-address to me, and resending...assuming that keeps the message as
unimportable - forward as attachment is probably safer...
