Hi,
Did you see the Enable Editing message bar at the top of the Excel window? If yes, you can click it to enable edit directly.
You can also change the trust center setting in Excel.
Go to File- Options- Select Trust Center and then click on Trust Center Settings...- Choose Protected View from the list
-Uncheck the boxes for:
Enable Protected View for files originating from the Internet
Enable Protected View for files located in potentially unsafe locations
Enable Protected View for Outlook attachments
-Click OK to save the changes.
I also suggest you check if the Workbook is blocked. Right-click on the Excel file in Windows Explorer- Select Properties- Check the Unblock option under the Security section if it is available.
