I assume it gave you this answer:
Open Control Panel: Press Windows + R, type Control Panel, and press Enter. Set Default Programs: In the Control Panel, go to Programs > Default Programs > Set Default Programs. Select Outlook: Find and select Microsoft Outlook from the list of programs. Click Set this program as default. Verify in Excel: Open Excel and try to send an email (e.g., File > Share > Email > Send as Attachment) to ensure Outlook is now the default email program.
