Exchange 2010 SP1 Mailbox Folder Permission


Sometimes in Microsoft Exchange environment we need to add user permission to other user mailbox.

We can add Full Access permission to mailbox like below:

Add-MailboxPermissions -Identity Mailbox1 -User JSmith -AccessRights FullAccess -InheritanceType all


But what if we don’t want to add permissions to all folders in mailbox but only to a one mailbox folder.

With Microsoft Exchange 2010 SP1 we can add permission to specified folder for user or Security Group, (Add-MailboxFolderPermission) we can remove (Remove-MailboxFolderPermission) and also we can change this permissions (Set-MailboxFolderPermission).

To add Reviewer permissions to User1 on Inbox folder of mailbox “John Smith” we can use:

Add-MailboxFolderPermission -identity\Inbox -User User1 -AccessRights ReadItems


Now we can check permissions to John Smith Inbox folder like below:

Get-MailboxFolderPermission -Identity\Inbox


We can change permissions for User1 to mailbox Inbox folder using Set-MailboxFolderPermission from Reviewer to FolderVisible:

Set-MailboxFolderPermission -Identity\Inbox -User User1 -AccessRights FolderVisible
