This ist most likely the result of a misconfigured Exchange config or a wrong address book entry in outlook of the sender.
Nothing special regarding the Blackberry.
You're suggesting the sender is using Rich Text format? I did suspect it was to do with that, but it doesn't seem like the same problem.
There is no attachment called winmail.dat that I can see, and unlike those seeing a winmail.dat file, we can read the message on a Blackberry, and can see the attachments too if we change to text view. Outlook has no problem reading the emails or the attachments.
While it may be true that the problem is a funny format being used by the sender, I fee that the Blackberry ought to be able to handle it. If the email really is in a winmail.dat attachment, then perhaps the Blackberry is doing well to open it, but has stopped short of being able to show attachments hidden within the file.
