Error: "not supported calendar message.ics" in Outlook 2007 clients


From within a program I create a calendar format information (an ics file) and send it to email recipients. This has been working very well with Outlook 2003 clients but Outlook 2007 clients are having problem. They get it as an attachment with the title:

not supported calendar message.ics

Is there a solution to this such as a SP or hotfix? Thanks in advance.

PS: The message format is iCalendar format and is exactly how it was suggested by MS itself using RFC 2445 in MSDN.
