Fix OneDrive Sync Pending

A shared document folder in our Microsoft OneDrive for Business has been stuck in “Sync pending — Shared” for several days. I have already restarted, reset, and fully re-connected OneDrive, yet the flag remains and new changes never reach the cloud.

I need someone who knows the OneDrive sync engine inside out to:

• Pinpoint the exact cause of the blockage—whether it’s cache corruption, permissions, throttling, or something deeper in the OneDrive for Business client.
• Repair the situation safely, preserving every file version and shared permission.
• Prove that the fix works by adding a test document, confirming it appears on another tenant account, and watching two-way updates flow without delay.

Please outline your direct experience resolving OneDrive or Microsoft 365 sync problems. If you normally use diagnostic tools such as OneDrive troubleshooting logs, ODSync /reset, PowerShell, or SharePoint admin centre reports, mention that briefly so I know you have the toolkit ready.

Acceptance criteria
1. “Sync pending — Shared” message cleared on my machine and any co-owner’s machine.
2. No document loss or permission changes.
3. Subsequent edits sync within normal latency for at least 24 hours.

Remote work via screen-share is fine; we can schedule around UTC+1. I will provide admin credentials as needed once we start.
