Totally new to this group, so please forgive the ignorance of the
question... =)

We are using Exchange 2k3 with Outlook2k3. The client side permissions
are not taking effect.

I.E. everyone is set to none and still anyone can add/read entries into
anyones calendar.

I read somewhere that it might be that Permissions are set too loose at
the mailbox/recipient container level, in this case I just wanted to
find out what to start with. Also, I;m assuming its possible to
override all client side permissions set by implementing it on the
exchange side ?

Any help/response is greatly appreciated.
