# Outlook review

Microsoft's free webmail, calendar, and contacts client, with ad-free and 100GB-mailbox upgrades bundled into Microsoft 365 from $9.99/month.

By Noah — last updated & pricing verified September 15, 2026.

> **Outlook** is Microsoft's email, calendar, and contacts application, offered as free ad-supported webmail (Outlook.com) and as a desktop/mobile client bundled into Microsoft 365 subscriptions with an ad-free inbox and larger storage.

Beyond sending and receiving mail, Outlook integrates a full calendar with scheduling and meeting invites, a contacts/people directory, and task management, all synced across web, desktop, and mobile apps. On Microsoft 365 plans, Outlook gains Copilot AI features for drafting, summarizing, and replying to email, along with 100GB of mailbox storage instead of the free tier's default allotment. It's used by individuals as a personal webmail client and by Microsoft 365 subscribers and businesses as the default email app tied into the rest of the Office suite, including Word, Excel, PowerPoint, and Teams.

## Facts

- Website: https://outlook.com
- Pricing: Free tier · paid from $9.99/mo (verified undefined NaN, NaN)
- License: Freemium
- Platforms: web, windows, macos, ios, android
- Best for: individuals who want a free, ad-supported webmail and calendar client, with the option to upgrade to an ad-free inbox, larger storage, and Copilot AI through a Microsoft 365 subscription
- Standout feature: Unified email, calendar, contacts, and (on Microsoft 365 plans) Copilot AI drafting in one interface, tightly integrated with Word, Excel, and Teams rather than functioning as a standalone mail app.
- Biggest weakness: The standalone, low-cost Outlook.com Premium subscription was discontinued for new users in 2017, so removing ads and getting 100GB of storage now requires a full Microsoft 365 subscription starting at $9.99/month rather than a cheaper email-only upgrade; reviewers also report slowdowns and sync issues with large inboxes and unreliable attachment search.
- Third-party ratings: Capterra 4.5/5 (2,501 reviews)
