Your company has an Exchange Server 2013 organization named Contoso. A partner
company has an Exchange Server 2013 organization named Fabrikam. Neither company
has any trusts between their forests. Users from both organizations access their mailbox
from the Internet by using Outlook Anywhere. You need to ensure that the users from both
organizations can share free/busy information. Which two cmdlets should you run? (Each
correct answer presents part of the solution. Choose two.)
A.
New-AcceptedDomain
B.
Add-AvailabilttyAddressSpace
C.
Set-AvailabilityConfig
D.
New-SharingPolicy
E.
Add-ADPermission
Explanation:
B: Use the Add-AvailabilityAddressSpace cmdlet to define the access method and
associated credentials used to exchange free/busy data across forests.
D: Use the New-SharingPolicy cmdlet to create a sharing policy to regulate how users inside
your organization can share calendar and contact information with users outside theorganization. Users can only share this information after federation has been configured in
Exchange.
B&C
Why?

Why not use New-SharingPolicy and specify the partner domain name in the -Domains parameter together with the level of access such as “FB only” or “FB with subject and location” etc…
New-SharingPolicy -Name “Contoso” -Domains ‘mail.contoso.com: CalendarSharingFreeBusyDetail’
Agree with Ty. There’s nothing mentioned about a federation trust. You need to use B&C in conjunction to establish free/busy where each forest will provide account creds to each other. I’ve used this method in production environments and it works great. Just need to make sure each sides CAS servers can talk to each other over port 443. Since both sides use Outlook anywhere this access is already open.
