Setting up Mailbox Folder permissions

It is possible to further restrict the access of users to specific Mailbox folders using the Add-MailboxFolderPermission cmdlet in Powershell. The Add-MailboxFolderPermission allows you to specify folder-level permissions for users, to a mailbox. Utilise this for more granular control over what users have access to.

Start by adding a user as a calendar delegate to a calendar with access to private items via PowerShell. The example below adds service_account@example.com as a calendar delegate to professional@example.com with access to private items.

Add-MailboxFolderPermission -Identity professional@example.com:\Calendar -User service_account@example.com -AccessRights Editor -SharingPermissionFlags Delegate,CanViewPrivateItems

Editor is the access right necessary to allow a user to create, delete and read calendar items. If you wanted the user to be able to create calendars, change Editor to PublishingEditor.

Further information on the the Add-MailboxFolderPermission and additional parameters is available from Microsoft.
