Hi, Is there any shortest way to give full permission to whole domain users in a room mailbox. Normally we used to add permission for a user or a group using Add-mailboxpermission.but i want to add whole domian user to be add in a single shot. is it possible? Exchange version: Exchange 2007 Regards Jeevananthan S

Perhaps the easiest way would be to simply set the folder permissions Default to "Owner", rather than giving full mailbox perms.

Hi Jeevananthan, PFDAVAdmin tool will help you grant folder permissions to all users.

Hi Andy, i have changed the Default to "Reviewer" so that all the user can see the the mailbox calendar... But the users are still not able to add the mailbox calendar to their outlook. is there any other way to proceed this?

Hi Serena Li, Let me try using the PFDAVAdmin and get back to you.. Regards Jeevananthan S

Depending on your Exchange version you may consider exfolders instead of pfdavadmin: http://blogs.technet.com/b/exchange/archive/2009/12/04/exchange-meet-exfolders.aspx Mike Crowley Check out My Blog!
