Exchange 2003 +Outlook 2003 permission problems

[Dos_Box]

All of our staff have shared Outlook calendars with other staff hosted on Exchange 2003. The default permissions for these is 'Reviewer' (View calendar folder and read contents), but it seesm that everyone can also edit everyone elses calendar!

Has anyone else encountered this, or is there a cascading permissions thing going on elsewhere? Anyway, I need to make them read only and can't find out how.

I had a problem a while ago where everyone could access everyone elses mailboxes. I only found this when I was trying to sort out a send on behalf of problem. I ended up locking the store which didn't allow me to backup or restore and had to redo the whole server and use a program to extract the mailboxes from the database files. Nice program, cost a fortune.

 

Have you checked the permissions in Users and Computers for their rights?

Are you editing the permissions at:

 

Exchange System Manager > Administrative Groups > YourAdminGroup > Folders > Public Folders > YourSharedCalendar, Properties > Permissions > Client Permissions

 

or in some other way? When I've made changes there they seem to have worked. Maybe try looking through the Administrative Rights... bit of that dialog box too to see if anything is awry.

No, permissions should be set in the user manager under the Exchange tabs. It does seem however that the 'Authenticated Users' group has full permissions. I wonder if this covers everyone who has logged on via AD?

Yes, Authenticated users covers anyone who's logged into the domain. It also applies to machine accounts.
