Excel FAQs About Excel Lost Saved Progress and Corrupted Tab Content Due to Account Conflicts
Why did Excel delete my second tab and move its content to the first tab after saving?
When multiple Microsoft accounts (e.g., personal, work, and client O365 licenses) are logged in simultaneously, Excel's AutoSave cache can split its upload paths. It fails to register the new XML structure (the second tab) but dumps the cached text payload onto the only recognized directory (the first tab). Removing overlapping licenses via Command Prompt fixes this.
If Version History shows no older versions, is my lost saved progress in Excel gone forever?
If the cloud Version History is empty, the file was never successfully synced to OneDrive/SharePoint due to the account mix-up. Your only actionable recovery method is to check the local Windows directory at %localappdata%\Microsoft\Office\UnsavedFiles for a cached draft.
Can I run 3 different Microsoft 365 licenses on one Windows PC?
No. Microsoft officially states you can only use a single O365 license on a Windows system at one time. If you need to access different organizational environments, you must use Excel for the Web in separate browser profiles, rather than connecting all three accounts to your desktop application.
How does WPS Office avoid the bug where saving, closing, and opening a file affects the content?
WPS Office uses a straightforward, localized save protocol that doesn't enforce continuous background license checks against multiple cloud tenants. When you save a file with new tabs in WPS, it writes directly to your storage drive without risking the cloud-sync cache conflicts inherent in O365.
