I`m trying to setup a resource mailbox to allow certain people to view the calender with a read permission can this be done. I`ve used the command set-mailboxpermission ``mailbox1`` -accesspermission readpermission -user ``user1`` but when I go to open the calender in outlook 2003 or 2007 it tells me I do not have permission. Help please

You need to use the -AccessPermissions FullAccess As I think ReadPermission only gives you permission to view the actual permissions on the mailbox Deli

If I give them fullaccess though that gives them also change permission within the mailbox. I don't want users changeing anything just view. Is there a cmd that would give a group read access to just the calender of a mailbox? Or do I have to go into each mailbox through Outlook and grant read access to the calender?

You must go into the mailbox and grant access on the calendar You might have a look at this script that can do that for you http://gsexdev.blogspot.com/2005/05/changing-default-permissions-on.html Deli
