Cause
Earlier versions of IIS include a wildcard character MIME mapping,
which permits IIS to serve any file regardless of its extension. IIS 6.0
does not include this wildcard character MIME mapping and does not serve
any type of extension that is not defined at the MimeMap node in the IIS
metabase.
Solution
Please see
Microsoft Knowledgebase Article: IIS 6.0 Does Not Serve Unknown MIME
Types (Article ID 326965) for instructions on adding MSG as a
permitted MIME type.
