About Microsoft Outlook
Outlook is Microsoft's email and calendar app. The mobile and desktop apps bring several mail accounts and calendars into one place, with a focused inbox that separates important messages, scheduling tools and attachments from OneDrive and other storage.
It runs on Windows, macOS, Android and iOS. The mobile apps are free, and the Google Play listing says Outlook is free for personal use with support for Microsoft 365 subscribers who gain extra features. The Windows and Mac desktop experience is tied to Microsoft 365 or Office licences, and prices are not supplied here. Google Play lists more than a billion downloads and the iOS app lists about 9.3 million ratings.
It suits professionals and students who work in Microsoft 365 and want mail, calendar and contacts together. A Microsoft account or work account is required, and the Android listing notes ads in the free experience. Outlook can also connect to Gmail, Yahoo and iCloud accounts.
There are several things called Outlook on Windows. Check which version your organisation expects before installing.
