Frequently Asked Questions

Will changing the Microsoft 365 organization name automatically update my OneDrive URL?

No. Changing the general organization name does not update your SharePoint or OneDrive URLs. Changing those URLs requires a separate, advanced SharePoint tenant renaming process via PowerShell.

What happens when I change an administrator's email address in Microsoft 365?

When you update an administrator's email address, they will be temporarily signed out of their current active session and must log back in using the newly updated email credentials.

Do I need special permissions to change the organization name?

Yes, you must be assigned the Global Administrator role within your Microsoft 365 tenant to access the 'Org settings' menu and modify the core organization profile information.
