E_SKYDRIVE_UPDATE_AVAILABILITY_FAIL
Within Windows cloud-file and sync-engine infrastructure, E_SKYDRIVE_UPDATE_AVAILABILITY_FAIL reports that changing the item’s availability state failed at an unspecified provider boundary. Diagnosis of this result should follow the original owner and generation rather than treating the visible symptom as the cause.
Mechanism behind the code
During a this result investigation, a Windows sync engine coordinates local NTFS objects, provider metadata, remote identifiers, quota and naming rules, placeholder hydration, network authentication, and asynchronous upload or download state. The same Explorer action can cross several of those boundaries, so diagnosis must retain the first failing stage rather than treating every code as a generic connectivity problem.
Availability changes can require hydration, dehydration, pin-state metadata, open-handle coordination, or service acknowledgement., because this HRESULT is broad, retain the nested provider or file-system status instead of assigning one cause from the outer value.
The first owner to inspect is the local sync root, placeholder state, file-system operation, provider request, network exchange, account policy, or remote storage operation that produced the HRESULT.
High-value telemetry
| Capture | Diagnostic value |
|---|---|
| Requested availability state for it. | This places the failure on the lifecycle or transaction timeline and helps test the Windows cloud-file and sync-engine infrastructure boundary. |
| Placeholder and pin state for it. | This separates caller input from environment and service state and helps test the Windows cloud-file and sync-engine infrastructure boundary. |
| Open handles and callbacks for it. | This provides a stable comparison across retries or another machine and helps test the Windows cloud-file and sync-engine infrastructure boundary. |
| Nested provider or Win32 status for it. | This identifies the exact object or resource generation involved and helps test the Windows cloud-file and sync-engine infrastructure boundary. |
Decision table
- Second supported path for the same stable item: for it, a changed result separates retained object, connection, path, host, or device state from the original input. Hold constant: for it, keep account, remote item version, and client build fixed.
- Reduced failing operation: If this result follows the reduced step, the rejecting transition is localized. Hold constant: for it, retain requested availability state and remove only unrelated work.
- Targeted corrective control: Use this as a diagnostic branch rather than a blanket workaround: query current placeholder state. Hold constant: for it, keep the original this result sample available for the final regression test.
Safe reduction procedure
When it is returned, use a disposable control object, repository copy, file, or device association where the subsystem permits it.
- First: Query current placeholder state.
- Next: Repeat on a closed disposable file.
- Then: Separate local pin metadata from network transfer.
- Finally: Capture the first callback failure.
Do not erase the distinction
During a it investigation, FILE_NOT_UPLOADED gives a specific prerequisite; UPDATE_AVAILABILITY_FAIL does not identify which availability substep failed.
Do not delete and redownload the item before preserving its placeholder and provider evidence.
Successful outcome
Verify it with the original scenario, one boundary case, and one deliberate failure; success means pin or unpin reaches the requested stable state and survives close, restart and offline/online transitions.
