Pinned File List Clearing in Excel Smart Phone App

Hi! Chuck. Thanks for the details. I'm here to help.

Here’s a detailed but concise summary of why pinned or recent files may disappear in the Excel mobile app:

1. App Data Cleared – If Excel’s cache/data is wiped (manually, by a cleaner app, or by the OS), pinned and recent lists are deleted since they’re stored locally. Fix: Avoid clearing Excel data or disable optimizer/cleaner tools.
2. App Updates or Reinstallation – Major updates or reinstalling the app resets local settings, including pinned lists. Fix: Re-pin files after updates; avoid unnecessary reinstalls.
3. Account Sign-Out or Switch – Logging out, switching accounts, or password changes can clear lists tied to the previous account. Fix: Stay signed in with the same account whenever possible.
4. Cloud Access Issues (OneDrive/SharePoint) – If pinned files are online and the app loses access (network issues, permission changes, file moved/renamed), they may vanish from the list. Fix: Ensure stable sign-in and cloud connectivity.
5. Bugs or Corrupted App State – Occasionally, updates or internal errors corrupt app data, clearing recent/pinned files. Fix: Keep Excel updated; reinstall if the problem persists.

See if this helps. If you need further assistance, just let me know.

Best regards,

Kimberly
