The quickest way to add Hotmail to iPhone

Open Settings on your iPhone, tap Mail, then Accounts, then Add Account. Choose Hotmail from the list of email providers. Enter your full Hotmail address and password, then tap Sign In. iPhone will verify your account and set up mail, contacts, and calendar access automatically — you don't need to enter server addresses or port numbers yourself.

The whole process takes about two minutes. If you have two-factor authentication turned on for your Microsoft account (which you should), you'll need to complete that verification step before iPhone finishes the setup.

Key Takeaways

  • Hotmail accounts added through Settings > Mail > Add Account use automatic setup and work with iPhone's built-in Mail app without extra configuration.
  • If automatic setup fails, you can manually enter your Hotmail details using IMAP settings, which keeps your inbox synced across devices.
  • Two-factor authentication on your Microsoft account requires you to verify your identity during setup, but you only do this once per device.
  • App-specific passwords are only needed if you use an older version of iOS or if automatic setup repeatedly fails.

What happens when you choose Hotmail during setup

When you select Hotmail from the account type list, iPhone connects to Microsoft's servers to verify your identity. This is different from manually entering IMAP or POP settings — iPhone is using what Microsoft calls OAuth, which means you're signing in through Microsoft's own login page rather than giving your password directly to the Mail app.

This method is more secure because iPhone never stores your actual password. Instead, it receives a token that lets it access your email without needing the password itself. If you ever want to stop letting iPhone access your Hotmail, you can revoke that token from your Microsoft account settings without changing your password.

When automatic setup doesn't work

If you tap Sign In and see an error message, or if the verification step fails, you can set up Hotmail manually using IMAP. Go back to Add Account, choose Other, then Mail, and enter these details: your full Hotmail address as the username, your password, and for the incoming mail server use imap-mail.outlook.com with port 993. For the outgoing server use smtp-mail.outlook.com with port 587.

Manual setup is less common now, but it's useful if you're on an older iOS version or if your Microsoft account has unusual security settings. IMAP keeps your inbox synced — when you delete or read a message on your iPhone, those changes appear on other devices too.

Two-factor authentication during setup

If your Microsoft account has two-factor authentication enabled, iPhone will prompt you to verify your identity during the sign-in step. You'll see a notification on another device you've registered (usually your phone number via text, or an authenticator app), and you'll approve the sign-in from there.

This happens only once per iPhone. After you approve it, iPhone stores the token and won't ask you to verify again unless you remove the account and add it back. Two-factor authentication protects your Hotmail account from unauthorized access, so it's worth keeping on even though it adds one extra step during setup.

Using app-specific passwords if needed

An app-specific password is a separate, randomly generated password that you create in your Microsoft account settings and use only for Mail on iPhone. You typically need this only if automatic setup fails and manual IMAP setup also fails, or if you're using an iPhone running iOS 13 or earlier.

To create one, sign into your Microsoft account online, go to Security settings, and look for App passwords under the two-factor authentication section. Generate a new password, copy it, then use that password instead of your regular Hotmail password when setting up Mail on iPhone. This password works only for that app on that device, so if someone finds it, they can't use it to access your Hotmail from a web browser or from another app.

What syncs and what doesn't

When you add Hotmail to iPhone Mail, the account syncs your email messages, folders, and read/unread status across all your devices. It also syncs your Hotmail contacts into the Contacts app and your Hotmail calendar into the Calendar app, so you see everything in one place.

Notes and tasks stored in Microsoft To Do or Outlook don't automatically appear in iPhone's Notes or Reminders apps — those are separate Microsoft apps you'd need to download if you want them. If you use Outlook.com's web interface to organize emails into categories, those categories appear as folders in iPhone Mail.

Removing or changing your Hotmail account

If you need to remove the account, go to Settings > Mail > Accounts, tap the Hotmail account, then tap Delete Account. This removes it from Mail, Contacts, and Calendar on your iPhone, but it doesn't delete anything from your actual Hotmail inbox — your emails stay on Microsoft's servers.

If you want to change which data syncs, go to Settings > Mail > Accounts, tap your Hotmail account, then toggle Mail, Contacts, or Calendar on or off. You can also change how far back iPhone syncs your email by tapping Mail Days to Sync and choosing a timeframe — syncing only the last month of emails uses less storage than syncing everything.

Frequently Asked Questions

Do I need to use my full email address or just the part before @hotmail.com?

Use your full email address, including @hotmail.com or @outlook.com. If you have a custom domain email through Hotmail, use the full address with that domain.

What's the difference between Hotmail and Outlook.com?

Hotmail and Outlook.com are the same service — Microsoft renamed Hotmail to Outlook.com in 2013, but old @hotmail.com addresses still work. Both use the same servers and settings, so it doesn't matter which name you use when setting up iPhone Mail.

Will my emails disappear from Hotmail if I delete them from iPhone Mail?

No. When you delete an email from iPhone Mail, it moves to your Trash folder on Hotmail's servers, just like deleting from the web. You can recover it from Trash within 30 days. The email stays on Microsoft's servers — removing the account from iPhone doesn't delete anything.

Can I add multiple Hotmail accounts to the same iPhone?

Yes. Repeat the setup process for each account. Go to Settings > Mail > Accounts > Add Account and choose Hotmail again. Each account appears separately in Mail, and you can switch between them by tapping the Accounts button at the bottom of the inbox.

Why does iPhone ask for permission to access contacts and calendar?

iPhone is asking whether you want Hotmail to sync your contacts and calendar into the iPhone's Contacts and Calendar apps. You can say yes to both, or toggle them off in Settings > Mail > Accounts if you only want email synced.
