A customer of mine contacted me today regarding an EventID 4027 from MSExchange ADAccess they wanted resolved. This error was being generated on all Exchange 2013 servers in their cluster.
After looking into the issue, I found that legacy Cross-Forest configuration remained in configuration partition from a previous Cross-Forest Exchange Migration. This is located under the Configuration --> Services --> Microsoft Exchange Autodiscover.
