Sharing activities history

Hi,
we have created a shared folder for a set of contacts (Exchange server).
I want to set up all the activities linked to a contact. A typical use would
be so that if a colleague is ill and we have a meeting set up with a contact
we can have a quick look at recent communications.
I read some previous threads that suggested this was not possible, but they
are 3 years old and I was hoping that there had been an update?!
We are using Outlook 2007.

Thanks,

Graeme
