Hi, Hamptonroad
Thank you for using Microsoft products and posting them to the community.
Are you sharing files in OneDrive or SharePoint?
You can refer to this article(Windows10):
Get notified when members of your team update your shared file - Microsoft Support
If you're on a new version of OneDrive, you can go to the OneDrive client and click Settings - Notifications to change it.
I hope the above information can help you. Feel free to send a message if you need further help.
Best wishes
