You have an Exchange Server 2013 organization that contains four servers.
All users access their email by using Microsoft Outlook 2010.
An administrator deploys a shared mailbox named Project.
You assign all of the users in the marketing department Full Access permissions to Project.
You discover that Project automatically appears in Outlook to all of the marketing department users.
You need to ensure that Project only appears in Outlook to the marketing department users who
add the mailbox manually to their Outlook profile.
Which two cmdlets should you run? (Each correct answer presents part of the solution. Choose two.)
A.
Remove-MailboxPermission
B.
Set-Mailbox
C.
Remove-Mailbox
D.
Add-MailboxPermission
E.
New-Mailbox
I disagree. You would Remove-MailboxPermission to remove the current Full Access. You would then use Add-MailboxPermission with the permission of Full Access and “-AutoMapping $false” parameter.
If you want to disable auto-mapping after assigning the permissions, you must first remove the permissions, then assign them again with the Automapping parameter set to $false.
When a user is assigned full permissions on a mailbox, the mailbox is automatically mapped
to the user’s profile.
You can configure the auto-mapping feature only when assigning the permissions!!!
Therefore, first Remove-MailboxPermission, then Add-MailboxPermission.
