Start by identifying the specific file in error before any re-uploading of the client.

Avant de commencer : adaptez toujours les commandes et manipulations à votre environnement. Sur un système de production, prévoyez une backup ou un retour arrière lorsque l’action peut modifier la configuration.

OneDrive: sync, paths and Files On-Demand

Technical checkpoints

  • Path limits include the full OneDrive/SharePoint path, not only the local filename.
  • Invalid characters, reserved names and SharePoint permissions can block individual items without stopping all sync.
  • Files On-Demand distinguishes online-only, local and pinned files; local disk usage therefore differs from cloud size.

Shorten a path

Count the full path and shorten repeated folder levels first rather than renaming randomly.

C:\Users\User\OneDrive - Company\...\file.ext

Topic-specific pitfalls

  • Resetting OneDrive can trigger a large rescan; save the error list first.
  • Moving a shared folder can break links and workflows even if sync resumes.

How to validate

  • The sync error list is empty and problematic files reach SharePoint/OneDrive web.
  • Paths remain within limits after including the local sync root prefix.
