Description:

The Group Policy setting requiring FIPS compliance prevents the recovery password from being saved to Active Directory. When operating in FIPS-compliant mode, BitLocker recovery options can be either a recovery key stored on a USB drive or recovery through a data recovery agent. Check your Group Policy settings configuration.

FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT

What BitLocker has already established

At HRESULT 0x80310038, BitLocker has determined that the requested export or escrow path would expose key material in a form disallowed by FIPS policy. The FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT code does not by itself say that the volume master key is lost or that user data is corrupt.

Operational boundary: FIPS-restricted key management.

For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, note: FIPS-restricted operation changes which protector, export and key-derivation paths BitLocker may use. When diagnosing FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, remember: The volume encryption algorithm and the protector workflow are separate layers, so a FIPS-related HRESULT should be traced to the exact protector or key-management call. For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, note: FIPS mode does not translate into “turn encryption off.” It constrains algorithms and key-handling paths, so the correct remedy is to select a permitted protector and escrow design.

Data to preserve before changing state

For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, record effective FIPS setting, requested protector/export type, target destination, account context and whether a data recovery agent is configured. For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, keep the full HRESULT and the first method that returned it because later cleanup calls can report a different state.
For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, capture manage-bde -status and the protector inventory for the exact volume GUID, not only the drive letter, because letters can change in WinRE, clusters and deployment environments.
Export BitLocker operational events for the FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT failure and note the boot session, caller identity and management source; that evidence separates this BitLocker condition from a generic access or storage error.

Related state to rule out

Do not merge this incident with failure to contact Active Directory or write a USB file; those are destination failures after export is permitted. If both appear with FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT in one trace, preserve ordering because the first HRESULT normally identifies the prerequisite that caused later cleanup or fallback messages.

How to retest without losing evidence

Select a permitted recovery design such as a compliant external key or DRA and validate escrow before changing active protectors.

After correcting the FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT prerequisite, refresh protection, conversion and lock state before one controlled retry; a cached UI message is not proof that the FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT condition is still active.
Before a FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT remediation deletes protectors, changes firmware mode, resizes partitions or decrypts a production drive, verify that an independent recovery method is available and escrowed in the intended directory or account.

manage-bde -protectors -get C:\ngpresult /h bitlocker-policy.html

For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, diagnosis should be driven by the target object, effective policy and captured state snapshot rather than by a generic remediation applied to every BitLocker error.

State checks specific to FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT

Checkpoint	How to interpret it for FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT
Before the call	Record the target identity and the pre-call FIPS-restricted key management state. For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, the decisive boundary is that the requested export or escrow path would expose key material in a form disallowed by FIPS policy.
At failure	Preserve effective FIPS setting, requested protector/export type, target destination, account context and whether a data recovery agent is configured. This proves whether FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT came from BitLocker itself or from a wrapper translating another result.
After correction	Select a permitted recovery design such as a compliant external key or DRA and validate escrow before changing active protectors. The FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT request should then advance without removing an unrelated recovery route.
After reboot or remount	Recheck protection, conversion and lock state for FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT; a successful management call is incomplete if the next boot cannot unlock the volume.

Verification after the change

For FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT, success means more than the absence of a dialog. Confirm that the condition represented by FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT now matches the intended design, that the protector inventory has not lost an independent recovery route, and that the next reboot or remount can unlock the volume. If the FVE_E_FIPS_PREVENTS_EXTERNAL_KEY_EXPORT request advances to another HRESULT, record both values in order because that transition reveals the next unmet prerequisite.
