6 The reason for this is that Microsoft Internet Explorer will not open

15 WORKAROUND
16
17 To work around this behavior, rename the .EML file that the URL
18 links to so that it has a .MHT file name extension, and then update
19 the URL to reflect the change to the file name. To do this:
20
21 1. In Windows Explorer, locate and then select the .EML file that
22 the URL links.
23 2. Right-click the .EML file, and then click Rename.
24 3. Change the file name so that the .EML file uses a .MHT file name
25 extension, and then press ENTER.
26 4. Updated the URL that links to the file to reflect the new file
27 name extension.

29 So... we do that. :)'''
