What happened?
An error occurred in your Excel workbook. If you added a table to the workbook since the last sync, this may be the reason why it won’t currently sync. To get the most current responses, delete the manually added table and try to sync again, or sync the data to a new workbook. Note the new sync won’t include any table you manually added to the previous workbook. To get a complete set of the most current responses, sync the data to a new workbook.
How can I avoid this?
If you've previously exported your form results to an Excel workbook, that workbook should stay in sync with the form unless you make manual changes to the workbook. For example, if you add your own table to the workbook or a formula to a cell, Forms won't recognize the new content and throw a sync error. Don't add additional content to your Excel workbook to ensure the data stays in sync with your form.
What happened?
An error occurred in your Excel workbook. The current workbook can't be opened in Excel Online due to your company policy, so data can't sync to the workbook. To get a complete set of the most current responses, sync the data to a new workbook.
How can I avoid this?
Your company policy may be preventing you from opening the current workbook you previously synced to. Check with your IT administrator to ensure you can access both form and workbook and learn more about files that have restricted permissions.
