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

Quota is a changing account-level resource. Parallel uploads, retention, recycle bins, or delayed accounting can make a prior estimate stale before commit.

Inspect 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.
  • Reported quota and timestamp.
  • Parallel reservations/uploads.
  • Remote retention or recycle-bin usage.

A controlled diagnostic sequence

  1. First: Refresh quota immediately before upload.
  2. Next: Account for in-flight reservations.
  3. Then: Free or expand remote capacity through supported means.
  4. Finally: Retry only after quota change is confirmed.

How to interpret comparison tests

Same stable item ID, second supported pathA change separates local file-system/provider state from remote service state.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.
