MSExchange ADAccess EventID 4027

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.


Simply remove the additional references to the legacy forest (the ones highlighted in yellow above).

Do not remove "Microsoft Exchange Online".  This is a default entry and is used when you create a Hybrid deployment with Office 365.
