FVE_E_AD_INSUFFICIENT_BUFFER

FVE_E_AD_INSUFFICIENT_BUFFER is primarily an API or management-tool error: the caller did not provide enough memory to receive the AD DS data returned by BitLocker.

For administrators and developers

  • For a script or management tool, inspect whether it follows the API size-query and retry pattern.
  • For an end user, this code usually points to the management software rather than a missing recovery key.
  • Capture the exact tool, command, and requested attribute before escalating to the directory or endpoint team.
