Move Onenote Classroom from one teachers OneDrive to another teachers OneDrive

Just adding another teacher will not move the file to another teacher's Onedrive.

The reason that he still has access is because the file is still on his OneDrive. When a teacher is leaving school, and a class notebook is on his Onedrive which you want to move then you should follow this procedure:

1. Have the leaving teacher share the folder where the class notebooks are stored (or let an admin do this).

2. The new teacher should create a new class notebook and add the students from the class.

3. Copy all student files from the shared folder from the leaving teacher to the new notebook location. The easiest way to do this is by using the "Open with explorer" feature in Internet Explorer.

4. When all files have been copied, delete or archive the old Class Notebook.
