Declutter your Microsoft 365 tenant
Stay productive and secure by removing clutter from your Microsoft 365 environment. Rencore Governance helps you identify orphaned resources, manage cloud sprawl, and restore accountability across Microsoft Teams, SharePoint, OneDrive, Entra ID, Exchange, Viva Engage, and Power Platform.
Clutter is not just untidy, it is unmanaged risk
Ownerless resources are unwatched risk
Teams and SharePoint sites without an owner keep their members, guests and data, with no one accountable when something goes wrong.
Sprawl buries the risk that matters
The more inactive teams and duplicate workspaces pile up, the harder it is to spot the one resource that genuinely puts your data at risk.
Stale accounts and devices widen the attack surface
Mailboxes and mobile devices that outlive their owners stay connected to your tenant, each one an entry point nobody is watching.
No one is accountable
Teams without any owner, and SharePoint site collections hosting more than 10 Copilot agents with no one accountable for them, make it difficult to assess value or take action. Rencore names the gap and the resource.

Microsoft 365 decluttering FAQs
What counts as clutter in Microsoft 365?
Resources that no longer serve a purpose but still live in your tenant: Teams and SharePoint sites without an owner, teams with no activity in six months or with just one or two users, mailboxes with no send, receive or read activity for 90 days, and devices that have not synced in as long.
How does Rencore find orphaned resources?
Pre-built policies continuously scan your tenant and flag inactive Teams, SharePoint sites, OneDrive folders and Exchange mailboxes, along with any resource that has no owner or no recent activity, so nothing gets left behind when projects end or users leave.
Can cleanup run automatically, or is it a manual project?
You can set up workflows that archive or delete unused items once a policy flags them, and automate lifecycle policies so resources are reviewed or retired on schedule. Cleanup becomes a standing policy rather than a recurring project.
Which Microsoft 365 services does decluttering cover?
Microsoft Teams, SharePoint, OneDrive, Entra ID, Exchange, Viva Engage and Power Platform, including the workflows, apps, workspaces and agents created in them.
Why does clutter matter for Copilot and AI agents?
Ownerless AI accumulates alongside ownerless content. Rencore flags SharePoint site collections hosting more than 10 Copilot agents with no one accountable for them, so you can assess their value and assign an owner before the estate grows further.
Will removing flagged resources disrupt users?
You stay in control of the action. Policies flag resources by inactivity and ownership first, and instead of deleting you can reassign ownership for Teams, SharePoint sites and Viva Engage communities, or archive items rather than remove them.
