You are the Enterprise Exchange Administrator of an Exchange Server 2010 SP1
organization.
You need to give a user in the Sales department access to a mail enabled public folder on
Server1.

How would you achieve this?

A.
Use the Add-PublicFolderClientPermission cmdlet.

B.
Use the Set-MailPublicFolder cmdlet.

C.
Use the Enable-MailPublicFolder cmdlet.

D.
Use the Update-PublicFolder cmdlet.

Explanation:
The full cmdlet string needed is: Add-PublicFolderClientPermission -Identity “\Sales Public
Folder” –User SalesUser -AccessRights Reviewer -Server “Server1”
If you need to give access to all folders beneath the top one, it can also be done with
AddUsersToPFRecursive.ps1 -TopPublicFolder “\Sales Public Folder” -User “Sales” –
Permission Reviewer, however, this need is not implicitly specified in the question, as far as I
recall.
