SharePoint library sync creates duplicate top level folders

Minimal guidance for messy support realities.

Scenario

A synced library appears twice in File Explorer with slightly different names, confusing users and causing edits in the wrong place.

Recommended Resolution Path

  1. Compare the library connection from the browser and the local sync client to identify duplicate mounts.
  2. Remove the stale sync relationship carefully so the active library remains intact.
  3. Check whether a renamed site or team changed the display name after sync was already configured.
  4. After cleanup, confirm users understand which path is authoritative.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
