Global Permissions
Read Free-Busy status
If a user editing a calendar event has the 'Read Free-Busy' permission for the attendee's mailbox the availability is displayed.
Send Mail As
When sending a new email message (from either SMTP, MAPI or WebMail) another 'From' address can be set if the user has the 'Send Mail As' permission for that mailbox.
Folder permissions
These permissions can be defined on both folder level and on mailbox level (in this case, they act on all subfolders in the user's mailbox). To share a folder right click on it and choose share..png)
Share a folder
To control a folder's sharing permissions, go to the tree folder on the left, right click on it and choose the Sharing option. When accessing Sharing options for a folder a list of the already defined permissions is displayed. If no permission has been previously set the list will be blank..png)
To edit an existing permission use its corresponding Edit button, to delete it hit the recycle bin shaped Delete button. Click the Add button to add a user or a group of users (only domain contacts are available) and set the permission level on the folder. There are 6 levels to choose from:
- No access (all permissions are denied)
- Viewer (view and read folder is allowed)
- Contributor (view, read folder and add items is allowed)
- Editor (view, read folder, set/clear flags, add items, mark items as deleted/not deleted and expunge is allowed)
- Master (all permissions are allowed)
- Custom (each permission is defined individually according to your needs)

Each permission may be allowed explicitly, denied explicitly or not specified. Permissions act hierarchically (are inherited on the group hierarchy). Additionally, resource hierarchies (a folder being parent to another folder) also benefit from the inheritance algorithm. In the Effective Permissions tab you will be able to see what permissions are specifically allowed or not.
