Hi,
To use the Windows 10 or iOS apps, you must sign in with a Microsoft account (Outlook, Hotmail, Live, Xbox, etc.) or an Office 365 account (personal, work, or school). To use the web app, you must sign in with a work or school Office 365 account (after your administrator has enabled the service).
You need to work with your administrator to add your live ID to the tenant and enable the service. Or as an alternative, try the Windows 10 or iOS app to log in using your Live ID.
