Frequently Asked Questions

Why does Outlook say my personal account is not activated?

Microsoft Office desktop applications require a paid license (such as a Microsoft 365 subscription) to remain activated. A standard free personal Microsoft account only grants access to the web versions of these apps.

How can I check if my Microsoft account has a valid Office license?

Log into your Microsoft account via a web browser, navigate to your account dashboard, and click on 'Services & subscriptions'. Here you can view any active Office licenses or subscriptions tied to your account.

Can I use Microsoft Outlook on my desktop for free?

The classic Microsoft Outlook desktop application requires a paid license. However, Windows users can use the free 'Mail' or 'New Outlook' app included with Windows, or use Outlook on the web at no cost.
