I have some old HTML messages, primarily I think from Eudora, which display as the HTML source code, and not as rendered text.



Some of them are OK, others just the HTML code stream.

Is there any way to force them to render?

One awkward way is to copy the body of the message (the HTML code) and save as a file, and then create a new message, and then attach file as "insert as text".

Any better solutions? And idea why this happened? (Outlook 2010)

A typical good email has headers that look like this:
Mime-Version: 1.0
Content-Type: multipart/alternative;
boundary="=====================_629154155==.ALT"
Content-Length: 5289


Bad ones like this:
Mime-Version: 1.0

Hi,

Make sure delete all messages from your Trash mailbox before you begin the import process.
1.Launch Outlook.
2.Make sure that you have closed all the folders in the folder tree. Select File | Import and Export.
3.Select Import Internet Mail and Addresses.
4.Click Next.
5.Select Eudora (Pro and Light) 2.x, 3.x, 4.x.
6.Check the data you wish to import—Import Address Book and/or Import Mail and click Next.
7.Click Finish
In order for Outlook to locate and successfully import your Eudora mailboxes and address book(s),
The files MUST reside in the C:\Program Files\Qualcomm\Eudora folder. If you store your mailboxes, address book, etc. on a network drive (e.g., H:\eudora), then you need to copy the following files from H:\eudora to C:\Program Files\Qualcomm\Eudora before you begin the import process to Outlook:
•*.mbx - mailbox files
•*.toc - table of contents files
•nndbase.txt - nickname file
•*.fol folders - Eudora folders containing mailboxes
•Nickname folder (if it is not empty)
•Attach folder (if it is not empty)
•descmap.pce - keeps track of your mailbox and folder list

Note: If you are not going to import all of your Eudora mailboxes and folders, open the copied "descmap.pce" file with Notepad and remove any mailbox and folder names that you are not going to import. If you don't, you will get an Import Error (e.g., The mail folder could not be opened. If another application is using this file, please close it and try again).

Thanks, but I no longer have the Eudora file system around, and just have some of these unconverted messages, that I did not notice when I first did the import.

Is there some way to export, and re-import individual messages to fix this?
