We have a site that has multiple companies with the same building; some of the offices have their own SBS domains for a handful of users. One of the users from the main network had been moved to an SBS domain and is accessing the local SBS/Exchange Server, they would like this user to have access to the original Exchange Server but he account setup fails, but the PC has network (ping) and DNS resolution to the Exchange Server in the other domain. This PC already has access to another Exchange 2010 server using outlook anywhere through a public IP address.
So to summarize, a PC in an SBS domain already has access to the local exchange account and another using outlook anywhere, but when they try to connect the client to the exchange 2013 server in another AD domain it fails, any ideas please?
