Outlook is our most full-featured email and calendar app, optimized for PCs and laptops.

If you're a heavy email and calendar user, and you want all the advanced features and capabilities of email, such as scheduling and task management, rich formatting, or mailbox rules, Outlook is the best choice for you.

You can use Outlook with your Office 365 account for business or with other accounts, such as Outlook.com.

For quick access to your email, calendar, and contacts on any computer with an Internet connection, sign in to your organization's Office 365 mailbox.

For example, if you’re on a business trip and only have access to a shared computer in a conference center, you can use Outlook on the web to securely access your emails.

Mail and Calendar apps provide basic email and calendaring features at home or work, best suited for your mobile devices.

These apps are touch-friendly and mobile optimized for simplified user experience, so no need for a keyboard or mouse. You can use and customize the swipe gestures to take actions like delete, flag, move, and so on.

The Mail and Calendar apps can be set up with your Office 365 account, Outlook.com (including Hotmail, Live, and MSN), Gmail, iCloud, Yahoo!, and other IMAP and POP accounts.
