Outlook for Windows 1.2026.818.0

The new Outlook for Windows is a unified mail and calendar client for Windows that consolidates personal and work accounts into a single app. It replaces the built-in Mail, Calendar, and People apps beginning in 2024 and is offered as a free, ad-supported application with optional Microsoft 365 subscriptions for an ad-free experience and expanded storage.

• Account integration: Combine multiple inboxes and calendars (Outlook.com, Gmail, Yahoo Mail, iCloud, and others) and switch between accounts without leaving the app.
• Composing and editing: Built-in suggestions and integrated spelling and grammar checks aim to produce clearer, more concise messages; some AI-powered features require a Microsoft 365 subscription.
• Attachments and file access: Attach documents and photos directly from the message composer, access OneDrive files from the inbox, and launch Word, Excel, and PowerPoint web apps for quick edits and comments.
• Productivity tools: Schedule sends, undo a sent message within a short window, and set follow-up reminders to keep conversations on track.
• Customization: Choose from multiple themes and fonts, pin important messages to the top of the inbox, and adjust message density with roomy, cozy, and compact view options.
• Cross-platform continuity: Syncs with free iOS and Android Outlook apps for a consistent experience across devices.
• Commercial model and requirements: The default free version displays ads for users without a Microsoft 365 subscription; purchasing Microsoft 365 Basic, Personal, or Family removes ads and increases mailbox storage.
