If you encounter that a resource’s calendar mostly shows just the organizer’s name within the subject this is most likely caused by a default setting of Microsoft Exchange. This behavior and a solution (Exchange 2010, 2013, 2016) is being addressed within KB2842288.
As the identity you can easily use the resource’s alias and are done. You might wanna write a PowerShell script if there are more than a few resources to go for.
