Feature comparison between new Outlook and classic Outlook

Applies To

Outlook for Microsoft 365 New Outlook for Windows

Last updated: September 23, 2026

The new Outlook for Windows brings you the latest features, Microsoft Copilot-assisted capabilities, and a new modern and simplified design to help you connect, organize, and get things done.

We've put together a feature coverage matrix to help you and your teams understand what's available and coming soon, compared to what exists today in the classic Outlook experience. Not all features and capabilities will be listed. See What's new for monthly updates.

Note

Some features are only available to individuals using a work or school account in Outlook with a qualifying Microsoft 365 subscription.

We are actively listening to your feedback and will make updates and changes to our feature roadmap based on what you tell us. If you have feedback on what we should consider adding to new Outlook, please use the in-app Help > Give Feedback link.
