E_SYNCENGINE_FOLDER_IN_REDIRECTION

The scope of E_SYNCENGINE_FOLDER_IN_REDIRECTION is Windows cloud-file and sync-engine infrastructure: the folder is currently being moved or redirected, so sync work must wait. Preserve 0x8802D00B beside the returning call before cleanup or retry creates a more generic secondary failure.

Read the condition first

Known Folder redirection, sync-root relocation, or provider-managed moves create a transitional namespace. Acting on old and new paths concurrently can duplicate or lose identity mappings.

Keep neighboring conditions separate

FOLDER_INACCESSIBLE is an access failure; FOLDER_IN_REDIRECTION is a temporary namespace transition.

Do not copy the tree manually while the managed redirection is active.

Incident record

  • Old and new folder identities.
  • Redirection operation and phase.
  • Pending file operations.
  • Provider generation and callbacks.

Reproduce without destroying evidence

The investigation should change one variable at a time and keep the original failing sample.

  1. First: Pause new work for the affected subtree.
  2. Next: Track identity through file IDs and operation IDs.
  3. Then: Resume after redirection commits or rolls back.
  4. Finally: Reconcile events from both path generations.

Three useful controls

  • Second supported path for the same stable item: a changed result separates retained object, connection, path, host, or device state from the original input. Hold constant: 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: retain old and new folder identities and remove only unrelated work.
  • Targeted corrective control: Use this as a diagnostic branch rather than a blanket workaround: pause new work for the affected subtree. Hold constant: keep the original failing sample available for the final regression test.

Definition of done

Closure requires the redirection completes atomically and every item retains one authoritative identity and location; then repeat the next lifecycle operation to detect stale state.
