Exchange 2013 and Exchange 2010 Trust RRS feed

  • Question

  • Hello,

    We have two separate domains (organisations) that are currently not linked and operate independently, however we want to share calendar and contact details (GAL) between each other.  One of the business has Exchange 2010 with AD and the other business has Exchange 2013 with AD.

    We have the option to setup a site-to-site link via our MPLS but unsure what is the best approach to achieve the objective described above, if anyone can help it would be greatly appreciated.

    Kind regards,
