Outlook is an email app that also contains a calendar. Besides Microsoft accounts, it can connect to Gmail and other email services, so you can read several inboxes in one place.
When you add another account, the app asks for permission to access that mailbox. Read what you are allowing, and remove accounts that you no longer use. Some advanced features need a paid Microsoft 365 plan.
Compare it with Gmail to see which fits better, and protect the account with two-step verification, as explained in our account guide.

When you add an account it asks permission to read that mailbox, so check what you are allowing and remove accounts you no longer use. Some advanced features require a paid Microsoft 365 plan.
Can Outlook manage Gmail? Yes, you can add Gmail and other accounts.
Is it free? The app is free to install; some features need a paid plan.
In practice: A person with a work address and a Gmail address connects both to Outlook, sees all meetings in one calendar and removes an old college account that is no longer used.
Compare with Gmail or Proton Mail. Add two-step verification as in our account security guide.
