Automapping feature in Exchange 2013

The automapping feature allows users who have "Full Access" permissions to another inbox(es) to automatically have those inboxes added to thier Outlook client.

In order to setup automapping we can use the Add-MailboxPermission cmdlet:
Add-MailboxPermission -Identity jbloggs -User 'Joe Bloggs' -AccessRight FullAccess -InheritanceType All -Automapping $true

And to disable automapping we can use the Set-MailboxPermission cmdlet:
Remove-MailboxPermission -Identity jbloggs -User 'Joe Bloggs' -AccessRight FullAccess -InheritanceType All -Automapping $false
Add-MailboxPermission -Identity jbloggs -User 'Joe Bloggs' -AccessRight FullAccess -InheritanceType All -Automapping $true
