We have a Bitlocker policy configured as shown in the image, but it's giving mixed results and I can't figure out why. For some devices the Recovery Key is stored in Azure AD + AD, while for other devices the Recovery Key is only stored in AD. The option: Require device to back up recovery information to Azure AD is enabled, all of the devices are encrypted and still 2/3 of the devices don't have a Recovery Key stored in AAD.
All devices are hybrid-joined, they all have the same autopilot profile, are in the same groups ...

    Hello @Bjorn Claes

    I would recommend with manual backup and setting for the Recovery Key backup to AAD.

    Please check the instructions and blog in https://learn.microsoft.com/en-us/answers/questions/579227/backup-bitlocker-keys-to-azure-ad.html

    Hope this helps with your query,

    If you are using the same policy across devices but getting different results, you're probably best of logging an Intune support case.

    The most likely cause here is that the device simply hasn't completed its HAADJ process when the recovery password is initially set (which is the only time that Windows will save the recovery password). The HAADJ process depends on a user logging into the device which is not in any way guarenteed.
