Extra text from headers,etc when Outlook 2003 Client sends calendar invite to Non-Outlook 2003 client

I am using Outlook 2003, only POP, no exchange. Anytime I send a calendar invite someone who does not have Outlook 2003, they get all of the headers, etc. Here is an example:

I took out the actual email addresses for confidentiality. What can I do to fix this. I assume I would need to fix this on the Outlook 2003 client. Thank you
