The fastest way to access Outlook

Go to outlook.live.com or outlook.com in any web browser, enter your email address and password, and you're in. If you've never signed in before, you may need to verify your identity — Microsoft will send a code to a phone number or backup email you have on file. If you're already signed in on that device, the page may skip the password step entirely.

You can also access Outlook through the Outlook app on your phone or computer. On Windows, search for "Outlook" in the Start menu. On Mac, look in Applications > Microsoft Outlook. On iPhone or Android, download the Microsoft Outlook app from the App Store or Google Play. The steps are the same: open the app, enter your email and password, and verify your identity if prompted.

If you're using Outlook at work, your employer may have set it up differently — you might sign in through a company portal or use a work account instead of a personal Microsoft account. Ask your IT department or check your onboarding email for the correct web address.

Key Takeaways

  • The web version is at outlook.live.com or outlook.com; the app version is available for Windows, Mac, iPhone, and Android.
  • You'll need your full email address and password; Microsoft may ask you to verify your identity the first time you sign in on a new device.
  • If you forget your password, use the "Can't access your account" link on the sign-in page to reset it through your phone or backup email.
  • Work Outlook accounts often use a different sign-in page — check your company's IT documentation or employee handbook for the correct address.

What to do if you can't remember your password

On the Outlook sign-in page, click "Can't access your account?" below the password field. Microsoft will ask you to enter your email address, then offer two ways to prove you own the account: a code sent to your phone number or a code sent to a backup email address you set up earlier.

If you don't have access to either of those, you can answer security questions you created when you first set up the account. Once you've verified your identity one of these ways, you can create a new password. Make it at least 8 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols — Microsoft will tell you if it's strong enough.

If you can't verify your identity through any of these methods, you may not be able to recover the account on your own. Contact Microsoft Support through their website, though recovery can take several days.

Signing in on a new device or browser

The first time you sign in on a device you've never used before, Microsoft usually asks you to verify your identity as a security step. You'll see a message like "We need to verify your identity" and be given options: receive a code by text message, receive a code by email, or answer security questions.

Choose whichever method you have access to. Enter the code or answer the questions, and you'll be able to finish signing in. On future visits to Outlook from that same device and browser, you usually won't need to verify again — unless you clear your browser's cookies or sign out manually.

If you're on a shared computer, always sign out when you're done. Click your profile picture in the top right corner of Outlook and select "Sign out". This prevents the next person who uses that computer from accessing your email.

Using Outlook with other email accounts

You can add non-Outlook email addresses to your Outlook inbox — Gmail, Yahoo, or any other provider. Sign into outlook.com, click your profile picture in the top right, and select "Settings". Go to "Mail" > "Accounts" > "Connected accounts", then click "Connect account".

Enter the email address you want to add and its password. Outlook will connect to that account and pull in your messages. You can read and reply to emails from that account right inside Outlook, though you'll still be signed into your main Outlook account.

This is useful if you have multiple email addresses but prefer to check them all in one place. You can set which account Outlook uses as the default for sending new messages, and you can remove any connected account at any time from the same Settings page.

Troubleshooting common sign-in problems

If you see "We don't recognize this location": Microsoft is blocking the sign-in because it looks unusual — maybe you're in a different country, or signing in from a new IP address. Click "I trust this location" or verify your identity with a code sent to your phone. After you sign in once, you usually won't see this message again from that location.

If the page won't load: Try a different web browser. If outlook.com doesn't work, try outlook.live.com. Clear your browser's cache and cookies — in most browsers, press Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac), select "All time" or "Everything", and check the boxes for cookies and cached images, then click delete.

If you're stuck in a loop asking for your password repeatedly: Sign out completely, close the browser, and try again in a fresh browser window. If that doesn't work, try the Outlook app instead of the web version. If the app also loops, your password may have been changed without your knowledge — use the password reset process described above.

If you see an error code: Write down the full error message and search for it on Microsoft's support website. Error codes like "0x80004005" or "AADSTS" have specific causes and fixes that depend on the exact number.

Setting up two-factor authentication for security

Two-factor authentication (also called two-step verification) adds a second layer of security: even if someone gets your password, they can't sign in without a code from your phone. To turn it on, sign into outlook.com, click your profile picture, and go to "Settings" > "Security" > "Advanced security options".

Click "Turn on two-step verification" and choose how you want to receive codes — by text message, phone call, or through the Microsoft Authenticator app. The Authenticator app is more secure because it works even if you don't have cell service, but text message is simpler if you're just getting started.

After you turn on two-factor authentication, you'll need to enter a code every time you sign in on a new device. You can mark a device as trusted so you don't have to verify every single time, but you'll still need the code the first time you sign in from that device.

Frequently Asked Questions

Can I access Outlook on my phone without downloading the app?

Yes. Open any web browser on your phone, go to outlook.com, and sign in the same way you would on a computer. The mobile website works on any phone. The app is optional — some people prefer it because it sends notifications and works slightly faster, but the web version is fully functional.

What if I have a Microsoft account but can't remember which email address I used?

Go to account.microsoft.com and click "Sign in". If you can't remember your email, click "Can't access your account?" and follow the recovery steps. You'll need to verify your identity through a phone number or backup email. If you don't have those either, Microsoft Support may be able to help, but recovery can take time.

Is it safe to save my password in my browser?

It's safe on a personal computer you control. It's not safe on a shared computer, a work computer, or a public computer. If you're the only person who uses your device, letting your browser remember your password is convenient. If anyone else uses that device, always sign out and don't save the password.

Can I use the same password for Outlook and other accounts?

You can, but it's risky. If one website gets hacked and your password is stolen, someone could use that same password to break into your Outlook account and all your other accounts. Using a different, strong password for each important account — especially email — makes you much harder to hack.

What happens if I haven't signed into Outlook for a long time?

Microsoft may temporarily lock your account if you haven't signed in for several months. When you try to sign in, you'll be asked to verify your identity through a code sent to your phone or backup email. This is a security measure to prevent someone else from accessing an abandoned account. Once you verify, you can sign in normally.
