Audit access to MS Forms data
Currently it is not possible for a Global Admin to audit the access to a Form's response data. According to Microsoft support, a Form is considered "Private data" despite being created on our organizational account and the audit log data being contained in the Office365 Audit Log.
There is no way for an administrator to view a Form created by an employee to determine who has been given "Collaborate" rights to a Form allowing them to view the response data. We are creating a few forms which collect information we deem sensitive and we need to be able to provide assurances to our business that only the authorized employees are able to view the response data for our organization.
