Question details

The user encounters a 'Refresh Recommended' prompt when trying to edit an Excel file accessed via Microsoft Teams, which prevents them from saving changes or uploading a copy.

How to Fix 'Refresh Recommended' When Opening Excel Files from Teams

Product: Microsoft Excel, Microsoft Teams
Device & OS: not provided
Scenario: Opening and attempting to edit an Excel workbook stored in SharePoint directly through the Microsoft Teams desktop application.
Observed behavior: Excel displays a 'Refresh Recommended' warning. The user cannot save modifications directly to the file, and using 'Save a Copy' fails to upload the revised workbook back to SharePoint.

Before you start

Before clearing your cache, manually save a local copy of your workbook to your computer to ensure you do not lose any unsaved changes during the reset process.

Solution 1Recommended

Clear Microsoft Teams and Office Document Cache

Clearing out corrupted temporary files in Teams and the Office Document cache usually resolves synchronization loops and allows the file to connect to SharePoint properly.

When you open files from Teams, the application caches data locally to improve loading speeds. If this cached data becomes corrupted or falls out of sync with the master file on SharePoint, it triggers the 'Refresh Recommended' error and blocks saving.

Close Microsoft Teams and Excel

Right-click the Microsoft Teams icon in your system tray (bottom-right corner of your screen) and select 'Quit'. Also, make sure all Excel windows are completely closed.

Clear the Teams Cache

Press the Windows Key + R to open the Run dialog. Type '%appdata%\Microsoft\Teams' and press Enter. Locate and delete all files inside the 'Cache' or 'Cache_Data' folder.

Clear Office Document Cache

Open the Microsoft Office Upload Center (or Office Document Cache settings depending on your Office version). Navigate to Settings and click 'Delete cached files'. Alternatively, clear temporary files via the Office suite settings.

Restart and Verify

Reopen Microsoft Teams and navigate back to your channel. Open the Excel workbook again to verify if the 'Refresh Recommended' error has been resolved and saving is functional.

Clear Microsoft Teams and Office Document Cache

Data Safety: Clearing the Teams and Office caches will not delete your messages, channels, or actual files stored in SharePoint. It only removes temporary synchronization data.

Solution 2

Verify Co-authoring Status and File Permissions

If caching is not the issue, conflicts in SharePoint co-authoring or restrictive permissions might be locking the workbook.

Frequently Asked Questions

Why does Excel in Teams constantly say 'Refresh Recommended'?

This warning occurs when your local cached version of the Excel file is out of sync with the master file stored on SharePoint. It is typically caused by corrupt temporary files in the Teams cache or unresolved co-authoring conflicts.

How do I save my work if the 'Save a Copy' feature is failing?

If 'Save a Copy' fails to upload directly to Teams, you should use 'Save As' to download a copy of the workbook to your local Desktop or Documents folder. Once saved locally, you can manually upload and replace the file in the Teams channel.

Does clearing the Microsoft Teams cache delete my chats or files?

No. Clearing the Teams cache only removes temporary background data used to speed up the app and synchronize files. Your chat history, account settings, and all files remain securely stored on Microsoft's cloud servers.
