Microsoft has fixed a known issue causing incorrect BitLocker drive encryption errors in some managed Windows environments.
"Affected environments are those with the 'Enforce drive encryption type on operating system drives' or 'Enforce drive encryption on fixed drives' policies set to enabled and selecting either 'full encryption' or 'used space only'."
The now-fixed bug only affects client platforms such as Windows 11 21H2/22H2, Windows 10 21H2/22H2, and Windows 10 Enterprise LTSC 2019.
Microsoft has resolved this bug in the KB5034204 preview update released on January 23 for Windows 11 and the KB5034763 cumulative update released on February 13 for Windows 10.
Admins can still mitigate the issue on Windows 10 Enterprise LTSC 2019 systems by enabling the "Not configured" setting for the "Enforce drive encryption on fixed drives" or "Enforce drive encryption type on operating system drives" policies in Microsoft Intune.
