Enable BitLocker with Intune only after recovery is proven

Source fact: what Microsoft documents

Microsoft Intune supports standard BitLocker, where users can see and interact with prompts, and silent BitLocker, which can encrypt a managed device without user interaction or local administrative rights. Microsoft identifies Endpoint security > Disk encryption as the focused policy surface and provides an encryption report for device status and recovery-key management.

For silent encryption, Microsoft documents supported Windows versions, Microsoft Entra join or hybrid join, TPM 1.2 or later, native UEFI, Secure Boot, and a configured Windows Recovery Environment. Silent enablement cannot require a TPM startup PIN or startup key because those require user interaction. Some Microsoft security-baseline settings can conflict by enabling those startup requirements.

Microsoft warns that suppressing the warning for other disk-encryption software allows BitLocker to continue even when another product is present. The result can include data loss, instability, boot failures, and complex recovery. Microsoft therefore directs administrators to identify and safely remove third-party encryption before silent deployment and to pilot representative devices.

Licensing and applicability

Applicable Intune licensing and a Windows edition that supports BitLocker management are required. Some settings require a supported TPM. Windows 10 reached end of support on 2025-10-14; although it can remain enrolled in Intune, Microsoft does not guarantee continuing functionality. Hardware capability, modern standby, policy type, recovery configuration, and user privilege affect encryption behavior. Personal Data Encryption on Windows 11 is a separate file-level feature and is not a replacement for BitLocker.

DSE recommendation: production-safe operational steps

Inventory Windows version and edition, join state, TPM, UEFI, Secure Boot, WinRE, modern-standby capability, current encryption, and every third-party encryption agent.

Define the recovery-key escrow location, authorized retrieval roles, identity-verification process, audit review, and post-recovery key rotation before enabling encryption.

Resolve duplicate BitLocker settings across Endpoint security, device configuration, security baselines, Group Policy, and scripts. Use one documented authority where possible.

Select representative pilot devices, including older hardware, standard users, remote users, and devices with important applications.

Verify key escrow before restart. Perform a controlled recovery test using the supported process, then confirm access and audit evidence.

Deploy the intended standard or silent policy, monitor encryption and error reports, and validate boot, sign-in, application, update, and remote-support workflows.

Expand in rings only after recovery and business-function exit criteria pass. Stop on unexplained missing keys, conflicting encryption, or boot failures.

DSE recommends never using an encryption-status percentage as the only success measure. A production-safe result requires encrypted devices, retrievable keys, authorized recovery, healthy restarts, and a tested response when a user reaches the recovery screen.
