Why Microsoft 365 data governance matters

Every file, team, and SharePoint site starts with good intentions. But over time, links stay open, guests keep access, and inactive workspaces linger.

ShareGate Protect helps IT teams uncover risky access, fix it in context, and prove progress with clear, shareable reports.

  • Find links that never expired.
  • Spot teams and sites with outdated permissions.
  • Identify guests who no longer need access.
  • Detect broad “Everyone” and “All Company” groups that expose too much.

Microsoft 365 access and sharing FAQs

What causes oversharing in Microsoft 365?

Oversharing usually happens gradually. As teams grow and projects change, links stay open, guest users keep access, and permissions don’t get reviewed often enough. Broad groups like “Everyone” or “All Company” also make it easy for sensitive files to be shared more widely than intended. Without continuous Microsoft 365 access reviews, these small gaps add up to real data exposure risks.

How does ShareGate Protect help manage Microsoft 365 access and permissions?

ShareGate Protect gives you one clear view of who has access to what across Teams, SharePoint, OneDrive, and Entra ID. Its Governance risk assessment highlights oversharing, outdated permissions, and risky guest access. From there, you can use in-context remediation, bulk actions, and smart recommendations to clean things up quickly and keep permissions right-sized over time.

Can I track inactive guest users with ShareGate Protect?

Yes. ShareGate Protect identifies inactive or unnecessary guest accounts across Teams and SharePoint so you can remove or review access with confidence. You’ll see which guests still have permissions, where they have them, and whether those workspaces are still active—making guest access management simple and reliable.
