Hello,
Thank you for your question and for reaching out with your question today.
The process to change the default save location is the same for all Office apps, including Word, Excel, and PowerPoint. Also, if you make one Office app save files to your local computer, all other apps automatically start saving files locally on your machine as well.
Here’s how you make that change in Word (which will auto-apply to all other Office apps):
Launch Microsoft Word on your computer.
Select Options from the left sidebar. If you’re on Word’s editing screen, select File > More > Options instead.
Select Save in the sidebar on the left of the Word Options window.
Enable the Save to Computer by default option in the Save documents section on the right.
Save your changes by selecting OK at the bottom of the window.
