- Open the site you want to report on.
- Click the cog icon to open Settings menu and then click Site usage.
- Scroll down to the Shared with external users section and click Run report.
- Pick a location to save the report and click Run report.
- Browse to the SharePoint Online location where you chose to save the report.
- Review the CSV report in Excel, filtering out default records (such as site Owners, Members and Visitors):
