During ODB migration, user encountered the below error during syncing
Status Code: Forbidden Microsoft.Graph.ServiceException: Code: accessDenied Message: Request was cancelled by event received. If attempting to delete a non-empty folder, it's possible that it's on hold
The error occurred because the target O365 tenant has the preservation policy enabled. Preservation policy will prevent user from deleting items from the recycle bin in SharePoint. This will need to be disabled for P365 to properly delete items if the items were deleted in the source and also during OneNote migration.
