Understanding SharePoint Domain Name Limitations and Changing Site Suffixes

Clarifies that the root tenant domain name cannot be changed, and provides the approved method for changing a specific site address suffix.

Microsoft does not allow changing the primary SharePoint tenant domain name (e.g., yourcompany.sharepoint.com) once it has been created. If your organization rebrands, the root domain remains permanent.

However, you can change the site address suffix for specific sites within your tenant. Changing a site address can impact synced folders, sharing links, and recently accessed files, so it should be executed carefully.

Access the SharePoint Admin Center

Log in to the Microsoft 365 admin center with administrator credentials and navigate to the SharePoint admin center from the left sidebar.

Select the target site

Go to 'Active sites' under the 'Sites' menu. Select the specific site you want to rename and click on it to open the details panel.

Edit the site address

On the General tab, locate the URL section and select 'Edit'. Note that if this option is disabled, your organization's retention policies, compliance locks, or the specific site type may be restricting this action.

Enter the new address

Type the new site address suffix, verify its availability, and save the changes. Allow some time for the Microsoft system to process the update and redirect existing links.

Important Mapping Note: Changing a site address suffix will automatically redirect most existing links, but users may need to restart their OneDrive sync clients to resume synchronization properly.

Frequently Asked Questions

Why is the Modify button disabled in my SharePoint admin center?

The Modify button for a site address can be disabled if you do not have sufficient administrator privileges, if the site is a special system site (like a hub site root), or if your organization's retention policies or compliance locks prevent URL modifications.

Will changing a SharePoint site address break my OneDrive sync?

Users will generally not lose data, but they may experience temporary sync interruptions. After a site address change, users might need to close and restart the OneDrive sync app, or in some cases, unlink and relink their accounts to recognize the new site address.

Can I migrate to a new SharePoint domain name if I really need to?

Since you cannot rename the root tenant domain in SharePoint, the only way to get a completely new domain name (e.g., changing from oldcompany.sharepoint.com to newcompany.sharepoint.com) is to create a brand new Microsoft 365 tenant and perform a full tenant-to-tenant migration of all your data.

Do shared links still work after changing a site address?

Yes, Microsoft automatically creates a backend redirect from the old site address to the new one, ensuring that previously shared links continue to function for users who have permission to access those files.
