What must be done before configuring device policies for iOS devices in the Sales OU?

To configure device policies specifically for iOS devices in the Sales Organizational Unit (OU), it is essential to turn on Advanced Mobile Management for that particular OU. This feature allows for the application of mobile device management (MDM) settings tailored to the devices and users in the Sales OU.

Enabling Advanced Mobile Management at the OU level is crucial because it enables the organization to manage mobile devices, enforce security policies, distribute applications, and control what features can be used on iOS devices specifically within that OU. It ensures that the configuration settings you apply will only affect the devices associated with the Sales OU.

While there may be other relevant settings or requirements for overall mobile management, this step is specifically tailored to the needs of managing iOS devices within a particular subset of the organization.
