Can You Change a SharePoint Domain to a Custom Domain?
Question details
The user wants to know if it is possible to change a SharePoint Online tenant URL from the default sharepoint.com extension to a fully custom domain.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Attempting to rebrand or customize the SharePoint tenant URL to match a company's custom domain for file sharing and internal sites.
- Observed behavior
- SharePoint Online does not allow replacing the .sharepoint.com portion of the tenant URL with a completely different custom domain, even if the domain is verified in Microsoft 365.
You must have Global Administrator privileges in the Microsoft 365 Admin Center to manage domain settings or initiate a tenant rename.
Rename Your SharePoint Tenant URL
While a fully custom domain is unsupported, you can change your SharePoint URL to another custom *.sharepoint.com domain.
Microsoft restricts removing the '.sharepoint.com' suffix for architectural reasons. However, if your goal is to update the company name in the URL, you can perform a tenant rename to change the prefix (e.g., from oldcompany.sharepoint.com to newcompany.sharepoint.com).
Sign in to the Microsoft 365 Admin Center, navigate to Settings > Domains, and add your new '.onmicrosoft.com' initial domain.
Open the SharePoint Online Management Shell and connect to your admin center using the 'Connect-SPOService' command.
Run the 'Start-SPOTenantRename' cmdlet with your new domain name. The rename process will run in the background.
Contact Microsoft Support for Advanced Options
If a tenant rename does not meet your rebranding requirements, consult Microsoft Support for advanced migration advice.

Frequently Asked Questions
Can I use my own domain for Microsoft 365 email addresses?
Yes, you can use a fully custom domain (like @yourcompany.com) for Microsoft 365 email addresses and user sign-ins. The custom domain limitation only applies to the SharePoint Online site URLs, which must retain the .sharepoint.com suffix.
Will renaming my SharePoint domain break existing sharing links?
Microsoft automatically creates redirects for your previous SharePoint site URLs, so most existing file and folder links will continue to work. However, some third-party applications or hard-coded links in external websites may require manual updates.
How long does a SharePoint tenant rename take?
The duration depends on the number of sites and the amount of data in your tenant. For small tenants, it may take a few hours, while larger organizations with thousands of sites might take more than 24 hours to fully complete the background renaming process.
