How works Free/busy between cross forest? RRS feed

  • Question

  • Hello,

    I have question about how works free/busy calendar share between cross forest?

    We have two domains (we are two sister companies):
    corp.company1.tld (emails : user@company1.tld), Exchange 2013 STD
    corp.company2.tld (emails : user@company2.tld), Exchange 2013 STD

    We have set :
    - TwoWay Domain Trust
    - RootCA across all servers
    - dns working from both sides
    - "autodiscovery.company1.tld" and "autodiscovery.company2.tld" works from both sides
    - we have set Availability service and AvailabilityAddressSpace on both sides
    - we have exported/imported SCP from one side to second sides (AutodiscoverConfig)
    - one server is opened to internet, second server is behind the firewall/antispam gateway, both servers is accessible on local network
    - we do not want Federation Sharing (MS Federation Gateway)

    And what should we do next? If I create on Exchange "company1.tld" MailUser contact "user@company2.tld", then I can't set calendar sharing for this user from Outlook and from OWA too.
    I can do only one thing : Publishing calendar, but this is standard function which not need trust and availability service etc.

    We using this howtos :

    So, what did I misunderstand?

    Thank you for tips.
