Our school has a Sharepoint site with 50 teachers in it. All of them are sharing documents and files with each other. Also, there is a calender wich is managed by one person. But the problem is, that everyone can put things in the calendar. Is there a way to configure the calendar, so only ONE person can make changes to the calendar? Now every teacher can change/add/erase appointments, and that's not wat we want.
Is this a SharePoint calendar? If so you should be able to edit permission for this.
A calendar is a list in sharepoint! You can set permissions on it by a imply going to the calendar, look in the ribbon and select 'Calendar' then 'List Settings' then 'Permissions for this list'. from there you can define the permissions
