Outlook 2007 - Calendar Sharing Permission Issue?

[Crispin]

Having a strange problem here, we are trying to share all the members of the IT support departments calendars through outlook 07.

We have sent share invites out and accepted all and each one had the message 'reviewer' when adding, so that should be right for read only.

When right clicking the shared calendar in the navigation pane, clicking properties and then permissions, it shows that the user has 'Read - Full Details' and no write permissions assigned.

So this should all be right but somehow we are still able to edit eachothers calendars. Maybe I'm missing something really obvious but none of us have had previous experience with this!

Could it be a setting within exchange?

Any help would be very..um..helpful.

Thanks

By 'we' who do you mean?

As an Exchange Administrator, you should have unquestioned access to anything Exchange related...

Sorry I'll clarify.
We want to sync 4 exchange accounts calendars. All accounts are owned by members of the IT support dept. including myself.
Our accounts would be members of the domain administrator group.

So is it not possible, since we're all domain admins, to prevent editing of eachothers calendars? My NM is adament that noone should be able to alter his calendar. He lives on outlook.

I've just played with it here, and for non-Exchange Administrators, the permissions seem to be working...

We are all specified somewhere in Exchange 2003 to be Exchange Administrators here, so we all have write access to any calendars even if the permissions are set to Reviewer.
