BitLocker backup into Entra ID
We are in the process of setting up Hybrid Join. When I try to backup the bitlocker key to Entra ID I get the following error in the event viewer
Failed to backup BitLocker Drive Encryption recovery information for volume C: to your Azure AD.
TraceId: *****************************
Error: Unknown HResult Error code: 0x80072efe.
When I run the backup powershell script on the computer i get the following error:
I have logged in with my FQDN on the computer. I show the computer is compliant and CO-Managed.
I have also blocked the GPO that was handling the bitlocker from being pushed to the computer. I have restarted and ran gpupdate /force multiple time. Any assistance would be helpfull.
I am unable to find anything online to resolve this issue.
- What is the status of BitLocker encryption on the device? Have you checked the BitLocker API event viewer log?
- The status of the BitLocker Encryption shows Fully Encrypted.
