Most mid-size and large organizations now carry two device populations: corporate endpoints managed end to end, and personal phones that touch company mail, chat, and files every day. Enrolling personal devices into full device management is politically hard and increasingly unnecessary. App protection policies (APP) in Microsoft Intune solve the narrower, more realistic problem: keep organization data inside approved applications on devices you never fully control.

This guide walks through the design decisions that matter when you build app protection policies for iOS/iPadOS and Android: which framework level to adopt, how to scope targeted and unmanaged apps, which settings differ per platform, how conditional launch behaves at runtime, where exclusions make sense, and how to phase from pilot to production without a support incident wave.
Why This Matters
App protection policies are the enforcement layer behind "MAM without enrollment" (MAM-WE). They are enforced by the Intune SDK inside compliant apps such as Outlook, Teams, OneDrive, Edge, and the Microsoft 365 mobile apps, not by the operating system. That means:
Organization data is encrypted in-app, behind an app PIN or biometric prompt, and blocked from leaking into unmanaged apps, personal cloud storage, or screenshots (platform permitting).
A selective wipe removes org data and policy-managed accounts from the app without touching personal photos, messages, or accounts.
Users on personal devices keep full control of the rest of the phone, which removes the main objection to BYOD.
Get the design wrong and you get the worst of both worlds: users who are annoyed by prompts and power users who route around the policy entirely, because one wrong setting (usually clipboard or "save as") pushed them toward workarounds.
Start from the Data Protection Framework
Do not hand-pick settings from memory. Microsoft publishes a data protection framework for Intune APP with three tiers, and each tier has concrete configuration values per platform. Treat the framework as your baseline and deviate only with a written reason.
Level
Intent
Typical audience
Level 1 (Enterprise basic)
Baseline org data protection: app PIN, encryption, no backup to unmanaged destinations
Most knowledge workers
Level 2 (Enterprise enhanced)
Adds data transfer restrictions: copy/paste controls, save-as restrictions, screenshot controls on Android
Regulated teams, finance, legal
Level 3 (Enterprise high)
Adds password/PIN tightening, block org accounts on jailbroken or rooted devices, stricter conditional launch
Privileged users, executives, high-risk roles
Design guidance: standardize on Level 2 for the broad workforce and reserve Level 3 for a defined group of high-risk users. Level 1 exists mainly as a compatibility floor for legacy workflows; most organizations that bother writing APP policies at all should start at Level 2.
Targeted Apps, Unmanaged Apps, and Policy Scope
An app protection policy has two app lists, and confusing them is the most common design error.
Targeted apps are the applications the policy protects: the Microsoft apps plus any line-of-business app built with the Intune SDK. The policy applies per organization identity inside those apps, not to the whole device.
Unmanaged apps (the exemption list) are apps you explicitly allow org data to flow into despite them being outside protection. Use this sparingly, for example permitting a specific internal app or the platform browser where a workflow demands it.
Data transfer controls, "Send org data to other apps" and "Receive data from other apps", should be set to policy-managed apps at minimum. If you must allow OS sharing (for example to open a file in the native browser), understand that you are trusting the OS share sheet as a boundary and that some Level 2/3 controls depend on staying inside the app ecosystem.
iOS and Android Settings That Diverge
The framework keeps both platforms close, but several controls are not symmetric. Design them per platform deliberately:
Control
iOS/iPadOS
Android
Screenshot blocking
Not enforceable by APP (OS limitation)
Enforceable: block screen capture and assistant capture
App encryption
Enforced by the Intune SDK within the app
Enforced via the app sandbox with policy-managed encryption
Save-as restrictions
Restrict "Save as" to policy-managed locations, including OneDrive/SharePoint connectors
Same intent, enforced through Android app data controls
Clipboard
Restrict cut/copy/paste between org and personal identities
Restrict plus can clear clipboard per policy
Enrollment interplay
MAM works for unenrolled and enrolled devices alike
MAM applies cleanly in the personal (unmanaged) profile; with enrolled devices the work profile changes the picture
Document these asymmetries in your design doc, because support tickets and security reviews will ask "can iOS users screenshot Outlook?" The honest answer is that APP cannot stop iOS screenshots; if that is a hard requirement, the device must be enrolled and managed, or you accept the residual risk explicitly.
Conditional Launch: Your Runtime Enforcement Layer
Data protection settings define the steady state. Conditional launch defines what happens when conditions drift: OS ages, the app falls below a minimum version, the user fails the PIN too many times, or the device is jailbroken/rooted. Each condition has an access action: Block access, Wipe data, or Warn (where supported).
Condition
Common production setting
Action
Min OS version
Current OS minus one major version
Block
Min app version
Vendor-published minimum (for example current Outlook version)
Warn, then block
Max PIN attempts
5 attempts
Reset PIN
Offline grace period
7-30 days depending on travel patterns
Block access
Jailbroken/rooted devices
Always
Block (Level 3: wipe org data)
Device model (iOS)
Optional allowlist for managed scenarios
Block
Two behaviors are worth calling out. First, PIN reset is friendlier than wipe and is the right default for most workforce groups; a wipe should be reserved for rooted/jailbroken conditions and specific high-risk populations. Second, the offline grace period directly shapes your travel and remote-work support load: a 30-day default sounds safe until a user returns from a two-month assignment and loses access in an airport. Set it per audience, not globally.

Common Exclusions: Users and Apps You Should Leave Alone
Real tenants need exclusions; pretending otherwise creates shadow IT. The recurring legitimate cases:
Shared mailboxes and service identities in Outlook. These accounts cannot complete interactive MAM registration the way a human can. Exclude the accounts (not the app) and protect the underlying mailbox with other controls.
Teams rooms, shared kiosk, and store-floor devices where the sign-in context is a room or device account.
Break-glass and emergency accounts, which must never be caught by protection or conditional access logic that could block incident response.
Targeted unmanaged app exemptions for one or two internal workflows, documented with an owner and a review date.
Track every exclusion in your design document with a reason and a review date, and audit them quarterly. Exclusions are the part of an APP design that silently rots.
Pilot to Production: Phasing and Reporting
Roll app protection policies out like any other access-enforcing control:
Define rings. IT and security, then executives and their assistants, then early-adopter departments, then the broad workforce.
Pilot on the pilot ring first with the framework level you intend to keep. Changing the level mid-pilot invalidates the feedback you are collecting.
Pair with Conditional Access in report-only mode. The Conditional Access grant "Require app protection policy" is what actually forces users onto protected apps; validate in report-only while you read the App protection status report (Microsoft Intune admin center → Apps → Monitor → App protection status) to see users with and without protection.
Watch the diagnostic signals: users hitting PIN resets, offline grace blocks, and conditional launch warnings. Tune before scaling.
Enforce with Conditional Access on the ring schedule, keeping "Require approved client apps" alongside "Require app protection policy" where your licensing supports it.
Review quarterly: framework level changes, new Microsoft app capabilities, and exclusion hygiene.
Best Practices
Adopt the published framework levels as-is; document exceptions instead of inventing a custom matrix.
Keep one policy per platform per level, assigned to the right groups. Do not multiply policies per department; settings drift between departments is unmanageable.
Prefer PIN reset over wipe for workforce users; reserve wipe for rooted/jailbroken and defined high-risk groups.
Set offline grace periods per audience based on travel and shift patterns.
Register every exclusion with a reason, an owner, and a review date.
Communicate the user experience (first sign-in, PIN setup, org vs personal separation) before each wave; most APP complaints are expectation gaps, not bugs.
Common Pitfalls
Assuming screenshot blocking works on iOS; it does not, and saying otherwise to a security reviewer damages trust.
Targeting service and shared accounts with interactive app protection, then debugging failed registration loops.
Deploying Conditional Access enforcement before reading the app protection status report, then locking out a department mid-migration.
Setting the offline grace period globally too short and bricking field users; too long and you weaken the control.
Exempting apps from data transfer rules "temporarily" without a review date, and finding the exemption two years later.
Does app protection policy require enrolling the device in Intune?
No. App protection policies work on enrolled and unenrolled devices alike, which is what makes MAM-WE viable for BYOD. The policy attaches to the organization identity inside the app, so the device itself can stay entirely unmanaged.
What exactly happens when I remove a user or issue a selective wipe?
A selective wipe removes organization data and the protected account from the targeted apps on the device, including policy-encrypted files and the org PIN. Personal data, personal accounts, and unmanaged apps are untouched. The data disappears at the next app launch or check-in.
Which users should get Level 3 data protection?
Reserve Level 3 for identities whose compromise has outsized impact: privileged IT administrators, executives, and teams handling regulated or high-value data. Applying Level 3 to everyone raises support volume without a proportional security gain, because most users do not handle data that justifies the tighter restrictions.
