E_SYNCENGINE_FILE_SIZE_EXCEEDS_REMAINING_QUOTA
E_SYNCENGINE_FILE_SIZE_EXCEEDS_REMAINING_QUOTA belongs to Windows cloud-file and sync-engine infrastructure. It marks the file fits the product limit but not the account’s remaining remote quota. The useful starting point is the exact API, object and state transition that returned 0x8802B002, because a shell or application message can hide that boundary.
Where this result is raised
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.
When it is returned, quota is a changing account-level resource. During a this result investigation, parallel uploads, retention, recycle bins, or delayed accounting can make a prior estimate stale before commit.
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.
Evidence worth collecting
- File logical size. for it, this separates caller input from environment and service state within the Windows cloud-file and sync-engine infrastructure boundary.
- Reported quota and timestamp. for it, this creates a stable comparison across retries or another machine within the Windows cloud-file and sync-engine infrastructure boundary.
- Parallel reservations/uploads. for it, this pins the event to an object or resource generation within the Windows cloud-file and sync-engine infrastructure boundary.
- Remote retention or recycle-bin usage. for it, this places the event on the lifecycle or transaction timeline within the Windows cloud-file and sync-engine infrastructure boundary.
A controlled diagnostic sequence
During a this result investigation, reduce the case while preserving the condition described by the HRESULT.
- First: Refresh quota immediately before upload.
- Next: Account for in-flight reservations.
- Then: Free or expand remote capacity through supported means.
- Finally: Retry only after quota change is confirmed.
How to interpret comparison tests
| Control | Interpretation | Hold constant |
|---|---|---|
| Same input, fresh object or connection | If the result disappears, retained lifecycle or ownership state is implicated. | While diagnosing this result, keep the original data, account, device, or timeline parameters unchanged. |
| Same object, reduced operation | If the result follows one specific transition, statement, file, or ceremony step, the failure is localized. | While diagnosing this result, remove only unrelated work and keep the first failing boundary visible. |
| Same stable item ID, second supported path | A change separates local file-system/provider state from remote service state. | While diagnosing it, keep account, remote version and client build fixed. |
What this code does not justify
FILE_SIZE_OVER_LIMIT is an intrinsic per-item limit; this code depends on remaining account capacity.
Do not repeatedly compress or rename the same file without changing the measured upload size or quota.
Verification after correction
Treat it as corrected only when the upload reserves and commits space atomically, and concurrent quota tests fail predictably; retain the original negative case so fallback cannot be mistaken for repair.
