Issue can't rename Sharepoint name [Moderator note: Personally Identifiable Information removed LTD to [Moderator note: Personally Identifiable Information removed

Hello @Ly Ouen (NP SECURE CO.,LTD)

To change your SharePoint domain name, you must first add an additional .onmicrosoft.com domain to your tenant.

As a Microsoft 365 administrator, go to Microsoft 365 Admin Center > Settings > Domains > select one of your existing onmicrosoft.com domains, and then choose "Add onmicrosoft.com domain (Preview)".

Once the new domain has been added successfully, you can proceed with renaming your SharePoint domain by using the SharePoint Online Management Shell.

For example, if you created the domain newtenant.onmicrosoft.com and would like the SharePoint domain rename to take effect on September 19, 2026, run the following commands:

Connect-SPOService -Url "https://tenant-admin.sharepoint.com"

Start-SPOTenantRename -DomainName "newtenant" -ScheduledDateTime "2026-12-31T10:25:00"

Please note that:

• Replace https://tenant-admin.sharepoint.com with your SharePoint Admin Center URL. You can find this URL when accessing the SharePoint Admin Center.
• The value specified for -ScheduledDateTime must be at least 24 hours later than the time you execute the command.
• The scheduled time is interpreted based on your local computer's date and time settings.

For detailed prerequisites, limitations, impacts, and step-by-step instructions, please refer to the following Microsoft documentation: Change your SharePoint domain name - SharePoint in Microsoft 365 | Microsoft Learn

If you are new to SharePoint PowerShell, I recommend reviewing the SharePoint Online Management Shell article before proceeding: Get started with the SharePoint Online Management Shell | Microsoft Learn
