Once a Delegate is configured for your mailbox, in the sense of configuring the checkbox mentioned above, the “Deliver meeting requests addressed to me and responses to meeting requests where I am the organizer to” option becomes available, and you can decide whether you, the delegate, or both should receive those. This option only becomes available in the UI when the Calendar folder permissions are set to Editor. Now, as the folder permissions are configurable via other means as well, what is usually referred to as Delegate is a user for which the “delegate receives a copy of meeting-related messages sent to me” setting is configured. The corresponding settings are shown on the screenshot below:

It’s easy to use this method to grant permissions on commonly used folders, but more importantly it allows you to control access to Private items and to configure the handling of meeting responses. While you can set folder level permissions by right-clicking any of your folders in Outlook and selecting the corresponding menu item, the Delegates dialog under File -> Account settings -> Delegate access exposes some additional controls. The access can range from being only able to read your messages, to being able to manage all your email as well as compose and send messages on your behalf. In the Exchange world, a delegate is a person you have given some level of access to over your own mailbox. We will take a look at them in a moment, but first, let’s try to explain what a delegate is and why the changes are important. Two parameters have been added to the *- MailboxFolderPermission cmdlets to facilitate those changes, namely the SendNotificationToUser and SharingPermissionFlags. In another example of a small, but impactful change, Microsoft has started rolling out improvements to the PowerShell cmdlets responsible for folder permissions that will allow us to manage some of the delegate-related settings.
