Appointments Bouncing back

[Khyron2]

Version: 2004
Operating System: Mac OS X 10.4 (Tiger)
Processor: Intel
Email Client: Exchange

The message contains a content type that is not supported
< #5.6.0 smtp;554 5.6.0
STOREDRV.Deliver.Exception:ObjectValidationException; Failed to process message due to a permanent exception

We have 5 Mac users all running Office 2004, off of our Exchange 2007 server. They've been working fine for months, when just the last week they all get the above bounce when trying to do meeting requests. They also bounce when trying to accept requests. All PC users are fine with Outlook 2003.

I googled and saw a couple of people with the same problem back in March but there was no solution posted.

Thanks in advance!

I suggest also posting your question in the
microsoft.public.exchange.admin newsgroup found here:

Hope this helps!
