We have one main office with exchange 2007 server running all roles hosting 2 smtp domains. Users there can access oof ok as using primary smtp address. We have a branch office that has vpn connectivity to the main office exchange server and there using 2nd smtp address as primary address.Clients with outlook 2007 and 2010 can not access oof. I believe this is because of using 2nd smtp domain as primary address and outlook cannot find autodiscovery properly.
I believe I need to set up redirection. I've tried creating forward look up zone in internal dns for 2nd smtp name adding srv record to dns to redirect this doesn't work. I've seen references to adding website and doing a redirect - Though this appears to be for external users only. The problem is internal for me at branch office.
