We have an exchange setup where mgmt for now does not want the users sending or receiving email, just use the calendaring & contact info within exchange 2003. Is there a easy way to prevent sending/receiving?

Well..... Exchange *is* an e-mail system.... I think this is the first time I have heard this request. Do they not want users sending e-mail to each other? Or to anyone? You could probably set the Delivery Restrictions for each user so that they could only send to the administrator, for example. Of course, each time someone tries sends an e-mail, they would get an NDR message back. You would do this on the Exchange General -> Delivery Restrictions option within Active Directory Users and Computers. This restricts WHO the user can receive mail from, but if it is blocked so that none of your users can accept mail from anyone, that might work. Another option that *might* work would be to go to the Delivery Options option and set the maximum recipients to 0. I have not tested that, but it might be a novel approach.
