Setting up Outlook on a computer or phone

Updated 9 November 2026 · How-to

Adding your work email to Outlook on Windows, Mac, iPhone and Android, and why we recommend the Outlook app on phones.

Your work email lives in Microsoft 365, so you can read it from any device once you sign in. On managed computers, Outlook is usually set up for you. This article is for adding email to a new phone, a home computer or a laptop we have not prepared.

On a Windows computer or Mac

Open Outlook. If it is the first time, it asks for an email address: type your work address, then your password, and approve the sign-in on your phone. If Outlook already has another account in it, go to File, then Add account on Windows, or Outlook, Settings, Accounts and the plus button on a Mac. Shared mailboxes that you have access to usually appear on their own after a few minutes.

On a phone

Install the Microsoft Outlook app from the App Store or Google Play and sign in with your work email. We recommend the Outlook app rather than the phone's built-in mail app, for two reasons. It supports the full Microsoft 365 security features, including the protections we can apply to keep company data separate from your personal apps. And it keeps your calendar, contacts and shared mailboxes in one place. Add the Microsoft Teams and OneDrive apps the same way if you need them.

In a web browser

From any computer, you can also go to outlook.office.com and sign in. This is handy on a shared or borrowed computer, but always sign out when you finish and do not let the browser save your password there.

If it keeps asking for your password

A loop of password prompts usually means a saved password is out of date or a sign-in is waiting for approval on your phone. Close Outlook, check your phone for a pending approval, and open Outlook again. If it still loops, contact us; do not delete and re-add the account, as that can remove local settings and signatures.

Personal devices

If you are adding work email to your own phone or computer, read Using your own phone for work first, so you know what we can and cannot see.
