Scenario: Migrating services and assets to a new custom domain after a Microsoft 365 tenant migration.

Solution 1Recommended

Update Domain References and Migrate Assets

Set your custom domain as the default, update user aliases, and address SharePoint dependencies before removing the NetOrgFT domain.

Removing a legacy domain like NetOrgFT requires clearing all references to it across your Microsoft 365 environment. SharePoint URLs cannot be changed with a simple domain switch and may require specific migration procedures.

Set Custom Domain as Default

Go to the Microsoft 365 Admin Center. Navigate to Settings > Domains, select your newly verified custom domain, and click 'Set as default'.

Update User Email and Proxy Addresses

Navigate to Users > Active users. Select the users still using the NetOrgFT domain and update their primary email address and aliases to use the new custom domain.

Address SharePoint Site URLs

SharePoint site URLs cannot be modified by just removing a domain. You must use the SharePoint Online Management Shell (PowerShell) to perform a tenant rename, or utilize a supported third-party tenant-to-tenant migration tool to move assets to the new domain structure.

Remove the NetOrgFT Domain

Once all users, groups, application dependencies, and SharePoint sites no longer reference NetOrgFT, return to Settings > Domains, select the NetOrgFT domain, and click 'Remove domain'.

Update Domain References and Migrate Assets

Important: If you receive an error when trying to delete the NetOrgFT domain, Microsoft 365 will typically provide a list of remaining dependencies (like specific users or groups) that still need to be updated.

Frequently Asked Questions

Why can't I delete the NetOrgFT domain from Microsoft 365?

A domain cannot be removed if it is still set as the default domain or if any users, groups, email aliases, or SharePoint assets are still referencing it. You must update or remove all these dependencies first.

Can I directly rename my SharePoint domain URL?

Microsoft provides a SharePoint Domain Rename feature via PowerShell for eligible organizations, but it has limitations. If your organization doesn't meet the criteria, you may need a supported tenant migration procedure.

Do I need to create new mailboxes for the custom domain?

No, you do not need to create new mailboxes. You can simply update the primary email address and proxy addresses (aliases) of your existing user mailboxes to the new custom domain.
