Access denied trying to enable BitLocker

I've configured Endpoint Manager to enable BitLocker silently on our Windows 10 PCs, but it's not working.

When I look in the Task Scheduler under Microsoft > Windows > BitLocker, there is a task called BitLocker MDM policy Refresh that is failing with the message 'Access is denied (0x8007005)'.

I'm assuming this task needs to run to enable BitLocker. Any ideas on how to fix this?

    Hello

    Thank you for your question and reaching out. I can understand you are having issues related to Access denied when enabling BitLocker.

    1. Please check if BIOS allow to you to enable the O.S. to manage the TPM technology, be sure you have enabled it, and disable the hard disk password protection when you encrypt it, and enable after encryption. And in be sure your account is inside Active Directory, enabled to deploy Bitlocker, and local computer manager.
    2. Uninstall any VPN software on the computer (you can reinstall after encryption). VPN can mess with BitLocker for some reason.
    3. Please update BIOS to Latest version from vendor website.
