A user enrolled their personally-owned iPhone in your MDM solution to access organizational services.

WithUser Enrollment, Apple provides a privacy-focused management model where organizational and personal data are separated using cryptographic containers. According to Apple Learning, when a user enrolls their personal iPhone, apps likeCalendar, Mail, and Notescreate distinct data silos for managed accounts. This ensures, for example, that corporate meeting invites remain in the managed calendar and cannot be copied into the personal calendar. Likewise, personal calendar events remain private and untouched by MDM controls. Safari data, bookmarks, and browsing history remain personal and are not cryptographically separated. Contacts are not universally separated either, unless tied specifically to managed accounts. The cryptographic guarantee applies most clearly to Calendar, ensuring compliance and protecting user privacy simultaneously.
