How to Fix Excel AutoSave Not Working for Files Opened in Teams
Question details
The user needs to restore AutoSave functionality for Microsoft 365 Excel files that are stored in Microsoft Teams and SharePoint.
- Product
- Microsoft 365 Excel, Microsoft Teams
- Device & OS
- Windows, Mac
- Scenario
- Collaborating on shared Excel workbooks stored in Teams, where users are trying to leverage automatic cloud saving across different operating systems.
- Observed behavior
- AutoSave stops functioning automatically for certain files when opened directly from Teams, despite the toggle appearing to be in the 'on' position.
Ensure your Microsoft 365 subscription is active, you are signed in with the correct account, and both your Excel and Microsoft Teams applications are updated to the latest versions.
Open the File Directly via the Excel Desktop App
Opening the file from the Excel desktop application rather than launching it directly from Teams can restore a stable AutoSave connection.
Microsoft Teams sometimes acts as a restrictive wrapper when opening files. Bypassing Teams and accessing the file directly through Excel's Recent menu ensures the desktop application can properly authenticate and sync with SharePoint.
Open the Microsoft Excel desktop application from your Windows Start menu or Mac Launchpad.
Navigate to the 'File' menu and select 'Open' from the left-hand sidebar.
Click on 'Recent' files or select your organization's SharePoint/Teams directory under the 'Sites' section.
Locate the affected workbook, open it, and check the top-left corner of the window to confirm the AutoSave toggle is properly engaged.
Verify File Format and Storage Location
AutoSave is only compatible with specific modern file types stored in supported Microsoft cloud locations.
Test for Platform-Specific Collaboration Conflicts
Conflicting edits or cached credentials between Windows and Mac users can sometimes cause the AutoSave connection to drop.
Experience Seamless File Saving and Collaboration with WPS Office
If you frequently encounter AutoSave glitches and collaboration errors in Microsoft Excel, consider switching to WPS Office. It provides a lightweight, highly compatible, and user-friendly alternative for spreadsheet creation and sharing without the heavy resource usage.
- 1. Download the Installer: Visit the official WPS Office website and click the 'Free Download' button.
- 2. Install the Software: Run the downloaded installer and follow the on-screen prompts to set up WPS Office on your device.
- 3. Enable Cloud Sync: Open WPS Spreadsheets, sign in to your WPS account, and activate WPS Cloud to ensure your files are automatically saved and backed up.

Frequently Asked Questions
Why does AutoSave turn off when multiple people are editing an Excel file?
AutoSave might disable itself if a collaborator opens the file using an unsupported older version of Excel, if legacy shared workbook features are active, or if someone in the session loses their internet connection, which halts the real-time sync.
Can I force AutoSave to turn on for local files?
No, the AutoSave feature in Microsoft 365 is exclusively designed for files saved in cloud environments like OneDrive, SharePoint, or Microsoft Teams. For local files, you must use the traditional 'Save' button or rely on the AutoRecover feature for disaster recovery.
How do I recover my work if Excel AutoSave failed while in Teams?
If AutoSave failed, you can check the file's 'Version History' under the 'File' > 'Info' menu. Alternatively, you can look for temporary unsaved files by navigating to 'File' > 'Open' and selecting 'Recover Unsaved Workbooks' at the bottom of the window.
