Microsoft is making the Outlook for Mac app free to use, the company announced this week. Previously available with a Microsoft 365 account or as part of the Office for Mac app suite, the Outlook app is downloadable from the Mac App Store and works with Outlook.com, Gmail, iCloud, Yahoo, and plain old IMAP and POP email accounts.

Microsoft already offers a free version of the Outlook client for iOS and Android, and it's currently testing a preview of a redesigned Outlook app that will replace the built-in Mail and Calendar apps that ship with Windows 11.
