To set up Outlook on iPhone, download the Outlook app from the App Store, open it and tap Add Account. Enter your email address, follow the sign-in prompts and approve any security check. To add more accounts later, tap Inbox, then Settings, Account, Add Account.
There are two ways to read Outlook email on an iPhone: Microsoft's Outlook app, or Apple's built-in Mail app. This guide covers the Outlook app, because it's the one that keeps your Focused Inbox, calendar and shared folders working the way they do on your computer, and it's the one most workplaces expect you to use.
How to set up Outlook on iPhone, step by step
- Download Microsoft Outlook from the App Store and open it.
- Tap Add Account. If you need a brand-new Microsoft email address, tap Create New Account instead.
- Outlook may suggest an email address it found on your phone. Tap Continue to use it, or Skip to type a different one.
- Enter your password and follow the sign-in prompts.
- If your account uses multi-factor authentication, approve the sign-in on your authenticator app or enter the code you're sent.
- Allow notifications when asked, so you don't miss new email.
How to add a second email account
- Open Outlook and tap Inbox (or your profile picture) at the top.
- Tap Settings.
- Tap Account, then Add Account, then Email Account.
- Enter the email address and follow the prompts.
You can add a work address, a personal Outlook.com address and even Gmail or iCloud to the same app, and switch between them or see them in one combined inbox.
Which accounts work, and how
| Account type | What to expect |
|---|---|
| Outlook.com, Hotmail, Live | Sign in with your Microsoft account |
| Microsoft 365 work or school | Sign in, then follow any extra steps your IT team requires |
| iCloud Mail | Sign in with your Apple Account and allow access, no app-specific password needed |
| Other IMAP or POP email | Choose IMAP if asked, and have your provider's server settings ready |
The catch: work accounts can need more than a password
If you're setting up a work email, the password often isn't the end of it. Microsoft explains that companies can add extra requirements: a company-managed phone, an older Exchange server, or app protection policies that control what you can copy out of work email. In practice that can mean installing Microsoft Authenticator or the Intune Company Portal app before Outlook will open your inbox.
If you see a message saying your organisation needs to protect its data, that's not an error. Follow the prompts, and if you get stuck, ask whoever looks after your company's IT. It's their policy, not a problem with your phone.
Settings worth changing once you're set up
- Notifications: choose whether you're alerted for every email or only Focused ones.
- Signature: replace the default sign-off with your own.
- Focused Inbox: keep it or switch it off, depending on whether you get lots of new enquiries.
- Calendar: connect your iPhone calendar if you want everything in one place.
- Swipe options: set left and right swipes to archive, delete or flag, so clearing email takes seconds.
Outlook app or Apple Mail?
Apple's Mail app can also show Outlook email, and Microsoft has instructions for that. It suits you if you want every account in one Apple app. The Outlook app suits you if you rely on Microsoft features like shared calendars, Focused Inbox or your company's security rules. For most business users, the Outlook app is less hassle, because some workplaces only allow work email in Microsoft's own apps.
If Outlook won't add your account
- Check you're typing the full email address, not just the name before the @.
- Sign in to Outlook on the web in Safari to confirm your password works.
- Make sure the Outlook app is up to date in the App Store.
- For a work account, ask IT whether your account allows phone access.
- Delete and reinstall the app if it keeps getting stuck on the same screen.
Using Outlook on iPhone day to day
Once your accounts are in, a few habits make the app far more useful. Use the search bar at the top to find emails, contacts and attachments without scrolling. Tap and hold an email to select several and archive them in one go. Use the calendar icon at the bottom to see meetings and join online calls straight from the event. And if you add more than one account, use the account picker on the left to switch between them or view every inbox together.
If you have a lot of email arriving on your phone, turning off notifications for anything except people you know is the single biggest favour you can do yourself. Constant alerts make email feel urgent when most of it isn't.
Keeping work email secure on your phone
- Turn on a passcode or Face ID for your iPhone if it isn't already set.
- Don't save work attachments to personal apps if your company's rules say not to.
- Remove the account from the app if you lose the phone or leave the job, and tell your IT team straight away.
- Keep both iOS and the Outlook app updated so security fixes reach you.

My verdict
Setting up Outlook on an iPhone takes about two minutes for a personal account: download the app, tap Add Account, sign in. Work accounts can take longer because of your company's security rules, so don't panic if you're asked to install another app. Once you're in, sort out notifications and your signature straight away.
