Exchange 2013 Multi-Tenant and intern OOF. RRS feed

  • Question

  • Hi, 

    I've build a Multi-tenant Exchange 2013 environment, which is working fine. But I'm still curious how everyone handles the internal OOF messages between two tenants. I read the the "Multi-Tenancy and Hosting Guidance for Exchange Server 2013". Microsoft says this about (internal) OOF:

    "A more performance impacting solution would be to create multiple transport rules using groups to control the deletion of the OOF messages. Again, this means no OOF messages are delivered between tenants on the same system."

    I was wondering, maybe there's a better solution?

  • I faced a similar design constraint with a multi-tenant system (2010 in my case). The only solution I could find (which I did not pursue) is to write a custom transport agent to forward messages to an external smart host, which then forwards them back into the organization.

    This makes the message look like it's external, rather than internal. I think this requires coding in C# or something.
