I have followed the various instructions around the net (specifically the TechNet article) on configuring MOSS2007 and Exchange for mail enabling your lists. I have also read and applied the changes specified by the Microsoft KB regarding the two forgotten Active Directory entries. At this point I am able to send an email to a list and have the email post. Some of my users want to make use of the Email enabled Calendar List. They create a standard Calendar list and mail enable it. They give the list a unique name for Active Directory. They then goto Outlook and try "inviting an attendee" to an event and wait to see the event get posted on the SharePoint list. I have applied the KB edits to the new Active Directory user and I can watch the emails come into the dropbox and then disappear, but nothing ever happens. I have permissions setup correctly as well as far as giving "Authenticated Users" contribute access.... I don't see any errors specifically.... I do notice all my emails come in as .eml attachments... Any ideas of where to look?

This indeed pointed to the correct solution. I logged onto the Exchange Mail Server. Using Exchange System Manager Expanded Central Exchange, Global Settings Right-Clicked Internet Message Formats -> New Input my SMTP server settings for the MOSS box And ensured MIME was checked with text-only and under Advanced, Exchange Rich-Text format -> Never Use.
