Mime Type Problems with Upload/Download Function

[an...@magnasteyr.com]

Hi!

I have implemented an upload Component into my application.
The user can also upload msg (MS Outlook) Files from there.

Do be able to download the file again, I have added the following line to my web.xml


  <mime-mapping>
  		 <extension>msg</extension>
  		 <mime-type>application/msoutlook</mime-type>
  </mime-mapping>


Now in Firefox everything works normal and the file is opened in MSOutlook, when I download it. 
But in IE the file isn't opened and i get a message, that its and unknown file type and I can't open the file

Any ideas, what I can do? Is it the false mime-type?
