BitLocker Support and Licensing for Microsoft 365 E1 and E3
Question details
Determine whether devices can utilize BitLocker encryption when subscribed to Microsoft 365 E1 or E3 plans.

- Product
- Microsoft 365 E1 and E3
- Device & OS
- Windows 10, Windows 11
- Scenario
- Verifying licensing eligibility and system requirements for device data encryption using BitLocker.
- Observed behavior
- Users need to confirm if BitLocker is supported directly via E1/E3 plans or requires specific Windows OS editions.
Ensure you have administrative access to your Windows device and verify your current Microsoft 365 subscription tier in the Microsoft 365 admin center.
Verify Windows Edition for BitLocker Compatibility
Check if your Windows edition supports BitLocker, as availability relies primarily on the OS version rather than just the Microsoft 365 E1 or E3 plan.
BitLocker availability depends primarily on your Windows edition (such as Windows 10 or 11 Pro, Enterprise, or Education) rather than solely on your Microsoft 365 E1 or E3 subscription.
While Microsoft 365 E3 includes some Windows Enterprise rights, you must still ensure your device is running a supported OS edition. Devices running Windows 10 or 11 Home do not support BitLocker drive encryption.
Click the Start menu, type 'Settings', and press Enter to launch the Settings application.
Navigate to 'System' and scroll down to select 'About' from the left-hand menu.
Check the 'Windows specifications' section to confirm you are running Windows 10 or 11 Pro, Enterprise, or Education.
If your edition is supported, open the Control Panel, go to 'System and Security', and click on 'BitLocker Drive Encryption' to manage your drives.

Try WPS Office for Secure and Lightweight Document Management
While resolving Microsoft 365 and BitLocker system requirements, consider WPS Office as a free, lightweight, and highly compatible alternative. It offers a familiar interface, seamless migration, and robust built-in document encryption features for your individual files.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installation package for Windows.
- 2. Install and Open: Run the installer and open WPS Writer, Spreadsheet, or Presentation.
- 3. Encrypt Your Documents: Go to the 'Menu', select 'Document Encryption', and set a password to securely protect your sensitive files.
