After furious head scratching, Stuart asked:

| From some people when I receive a meeting request it comes through as
| a regular e-mail, from other people it is processed correctly as a
| meeting request, prompts a response and is added to my calendar.
|
| For example: I send a meeting request to "Joe" he receives a proper
| meeting request. But when Joe sends me a request, I receive a
| regular email.
|
| When I send a request to "Tom" it works properly in both directions.
|
| Joe is sending from a large company with servers, etc. Tom is
| sending from a stand alone computer.
|
| Any thoughts about what is going on here?
