This policy setting specifies the school code that the Class Notebook Add-in for OneNote requires in order to call Rediker's Application Programming Interface (API). This policy setting is not required if the Class Notebook Add-in for OneNote is configured to connect to a different Learning Management Systems (LMS) besides Rediker. For more details, please refer to https://aka.ms/classnotebookaddingrouppolicy.
If this policy is enabled, users will not be prompted to enter a school code when they connect the Class Notebook Add-in for OneNote to Rediker. Instead, the school code will be obtained from this policy setting, allowing an administrator to control its value for an entire school or district. This also makes it easier to update the school code should its value change.
If this policy is disabled or not configured, the Class Notebook Add-in for OneNote will prompt the user to enter a school code. Should the school code change, users will have to manually change its value in the add-in.
