Hello,
Thank you for your post to the Forum.
When cloud-based Excel files go missing and you're seeing a message like “one or more accounts require re-login,” it usually means that your access to the storage service (like OneDrive or SharePoint) has expired or needs to be refreshed.
Steps to Reconnect and Recover Your Files
Re-login to your Microsoft account: Make sure you're signed in to all relevant accounts—especially the one tied to your Excel files.
Check for multiple accounts: If you’ve got personal and work accounts, make sure the right one is active. Sometimes switching between them can cause access issues.
Refresh the page or restart the app: Once you’ve logged in again, reload the file page or reopen Excel to see if your files reappear.
Look in OneDrive or SharePoint directly: Visit onedrive.live.com or your organization’s SharePoint site to check if the files are still there.
Try a different browser or device: Occasionally, browser cache or device-specific glitches can mess with file visibility.
