  • What do you mean by "calendar sharing"?  Free-busy?

  • Hi Juan,

    Use the Add-AvailabilityAddressSpace cmdlet to create availability address space objects that are used to share free/busy data across Exchange organizations.

    Below is Syntax 
    Add-AvailabilityAddressSpace -AccessMethod <PerUserFB | OrgWideFB | PublicFolder | InternalProxy | OrgWideFBBasic> -ForestName <String> [-Confirm [<SwitchParameter>]] [-Credentials <PSCredential>] [-DomainController <Fqdn>] [-ProxyUrl <Uri>] [-TargetAutodiscoverEpr <Uri>] [-UseServiceAccount <$true | $false>] [-WhatIf [<SwitchParameter>]]

    For more information check out and make appropriate modification per your environmental requirements :

  • Yes, that is required and you can configure what information you want to shared in between two domains.
