Question details

Users are noticing multiple SharePoint sites with the exact same display name in the Admin Center and need to know why they exist and if they can be safely removed.

Why Duplicate SharePoint Sites Appear in the Admin Center

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Reviewing and managing active sites within the Microsoft 365 SharePoint Admin Center.
Observed behavior: Two or more private SharePoint sites appear with identical names but possess different URLs, group email addresses, and Microsoft Teams connections.

Before you start

Before attempting to delete any identically named sites, ensure you have SharePoint Administrator privileges and be aware that deleting a site may also permanently delete its connected Microsoft 365 groups, shared inboxes, and Teams channels.

Solution 1Recommended

Identify the Source of the Duplicate Sites

Determine if the duplicate sites were automatically generated by other Microsoft 365 services like Teams, Planner, or Viva Engage.

SharePoint allows multiple sites to share the same display name as long as their underlying URLs are unique. Often, these are not accidental duplicates but rather intentional sites created by connected Microsoft 365 services.

For example, every time you create a private or shared channel in Microsoft Teams, a brand-new, separate SharePoint site is generated to manage the permissions of the files shared within that specific channel.

Access Active Sites

Log in to the Microsoft 365 Admin Center, navigate to the SharePoint Admin Center, and click on 'Active sites' under the Sites menu.

Compare Site URLs

Locate the sites with identical names and look closely at the 'URL' column. You will notice the URLs have slight variations or suffixes.

Check Microsoft 365 Group Associations

Review the 'Microsoft 365 Group' and 'Primary Admin' columns to see if the site is tied to a Planner plan, a Viva Engage community, or an Outlook group.

Verify Teams Channel Connections

Look for the Teams icon in the site list. Sites associated with private Teams channels will be linked to the parent team but operate as isolated sites to ensure privacy.

Identify the Source of the Duplicate Sites

Private Channel Architecture: Private channels require strict access control that differs from the main team. Microsoft achieves this by provisioning an entirely separate SharePoint site for each private channel.

Solution 2

Safely Delete Unused Duplicate Sites

Remove identical sites only after verifying they are empty and not connected to active Microsoft 365 resources.

Frequently Asked Questions

Can two SharePoint sites have the exact same display name?

Yes, SharePoint allows multiple sites to have the exact same display name as long as their backend site URLs and Microsoft 365 group email addresses are completely unique.

Why did a private Teams channel create a new SharePoint site?

Microsoft Teams creates a separate, dedicated SharePoint site for every private or shared channel. This architecture guarantees strict access control and security, ensuring that only specific members of the private channel can access those files.

What happens if I delete a SharePoint site connected to a Microsoft 365 group?

Deleting the site will also permanently delete the connected Microsoft 365 group. This includes its shared Outlook inbox, group calendar, Planner tasks, and any associated Teams channels. You should always verify site contents and connections before deleting.

How can I tell if a site is connected to a Microsoft 365 group?

In the SharePoint Admin Center, view the 'Active sites' list and look at the 'Microsoft 365 Group' column. If it says 'Yes' or lists a group email address, the site is bound to a Microsoft 365 group and its associated services.
