I have deleted a Group or Microsoft Team using ProvisionPoint actions or lifecycle policies, however I can still see an active Site. Why does this remain and what can I do to remove this?

Why does the SharePoint site still exists after Group deletion

1. Group deletion ≠ immediate site deletion

Deleting a Microsoft 365 Group (via Graph or otherwise) does not instantly remove the SharePoint site.

• The group is soft-deleted first (moves to “Deleted groups” for 30 days)
• Teams disappears almost immediately
• The SharePoint site is decoupled and queued for deletion, not instantly removed
  

 During this window:

• The site can still exist
• Permissions may still allow access (especially for Site Collection Admins)

2. SharePoint has its own deletion lifecycle

SharePoint Online manages sites independently:

• When a group is deleted, its site:
  • May remain active temporarily
  • Is later moved to the SharePoint “Deleted sites” recycle bin (93 days)

👉 This creates a gap where the group is gone but the site is still active

1. Files (Documents library used by Teams)
2. Channel folder structure
3. Possibly private/shared channel sites

3. Permissions can persist

Even if the group is deleted:

• Users who had direct permissions or were site admins may still have access
• The site isn’t immediately locked down

4. Background provisioning / deprovisioning delays

Microsoft 365 uses asynchronous backend jobs:

• Group deletion triggers:
  • Exchange cleanup
  • SharePoint cleanup
  • Teams cleanup (if applicable)

These processes can take minutes to hours to days (sometimes longer)

5. If retention policies were present (even if you think not)

Even if you believe no retention is applied, check carefully:

• Microsoft Purview retention policies
• Retention labels applied to content
• eDiscovery holds

👉 If any of these exist:

• The site will be preserved
• It may remain accessible or partially accessible

6. Orphaned site scenario

Sometimes the group is deleted but site deletion fails or is delayed, creating an orphaned SharePoint site.

This can happen due to:

• API-driven deletions via Graph
• Temporary service issues
• Dependency failures (e.g., Teams-linked site)

What can you do?

1. Wait, it is most likely going through the scenarios above and will need time to be processed.
2. Manually remove the Site.
