How to Audit Guest Access and External Sharing Across Microsoft 365
Pull guest users, sharing links, and collaboration settings from across Entra ID, Teams, SharePoint, and OneDrive into one governance workflow.
External collaboration is essential in Microsoft 365, but it can also become difficult to control if guest access and sharing settings are not reviewed regularly.
Guest users may remain in Entra ID long after a project ends. Teams guest access may be enabled more broadly than intended. SharePoint and OneDrive may contain sharing links that no one has reviewed in months. For admins, that creates both operational and security concerns.
Why this is hard to manage manually
The challenge is that external access is not limited to one place. To get a full picture, admins often need to review:
- Guest users in Entra ID
- Teams guest access settings
- External collaboration settings
- SharePoint sharing configuration
- OneDrive sharing links and external access policies
What a better governance workflow looks like
A stronger workflow should help you:
- Identify guest users
- Review external identities
- Export sharing link data
- Check tenant-level sharing settings
- Tighten exposure where needed
- Produce a report for follow-up or audit review
How PSForge helps
PSForge helps admins build Microsoft 365 governance workflows visually and generate the PowerShell behind them.
Using built-in tasks for Entra ID, Teams, SharePoint Online, and OneDrive, you can assemble a repeatable process for reviewing guest access and external sharing across your environment. That makes it easier to standardize reviews and reduce ad hoc scripting.
Example governance workflow
- Export guest users from Entra ID
- Review Teams guest and external access settings
- Export SharePoint sharing links
- Export OneDrive shared links
- Identify where external sharing is too broad
- Disable or tighten sharing where appropriate
Final thoughts
Guest access and external sharing are necessary in modern collaboration, but they should never be left unreviewed.
PSForge helps turn a messy multi-platform review process into a reusable PowerShell workflow that is easier to build, easier to repeat, and easier to maintain.
