Adding an Outlook account takes three steps: open Outlook, select Add Account, and sign in with your Microsoft credentials
If you have an Outlook.com, Hotmail, or Microsoft 365 email address, you can add it to the Outlook desktop app or mobile app in a few minutes. The process is straightforward because both your email and the app come from Microsoft — they're designed to work together without extra configuration.
The steps differ slightly between Windows, Mac, and mobile, but the basic flow is the same: open Outlook, tell it to add a new account, enter your email address and password, and let it connect. Most accounts set up automatically without asking for server addresses or technical details.
Key Takeaways
- Outlook.com, Hotmail, and Microsoft 365 accounts connect automatically to the Outlook app without needing server settings.
- You will need your full email address and password, and Microsoft may ask you to verify your identity with a code sent to your phone or recovery email.
- The Outlook app on Windows, Mac, iPhone, and Android all use the same basic setup process: Add Account, enter credentials, sign in.
- If automatic setup fails, check that you are using the correct password and that two-factor authentication is not blocking the connection.
Adding Outlook to the Windows desktop app
Open Outlook on your Windows computer. If this is the first time you are opening it, you will see a setup screen. If Outlook is already open with another account, go to File in the top left, then select Add Account.
Type your full Outlook.com or Hotmail email address in the box that appears. Click Next or Continue. Outlook will recognize it as a Microsoft account and ask for your password. Enter the password you use to sign into your Microsoft account (the same one you use for OneDrive, Xbox, or Windows itself if you signed in with that email).
Microsoft may ask you to verify your identity. If you have two-factor authentication turned on, you will receive a code on your phone or recovery email. Enter that code when prompted. Once verified, Outlook will connect to your mailbox and begin downloading your messages. This can take a few minutes if you have years of email stored.
Adding Outlook to the Mac desktop app
Open Outlook on your Mac. Go to Outlook in the menu bar at the top, then select Preferences. Click Accounts, then the plus sign (+) to add a new account.
Select Exchange or Office 365 from the account type list (Outlook.com and Hotmail accounts use the same protocol). Enter your full email address and password. Click Add Account. Outlook will verify your credentials and begin syncing your mail.
If you see an error about authentication, make sure you are using the password for your Microsoft account, not a separate Outlook password. If you have changed your Microsoft password recently, use the new one.
Adding Outlook to iPhone or Android
Open the Outlook mobile app. If you are setting it up for the first time, tap Add Account. If you already have an account in the app, tap the menu icon (three horizontal lines) at the bottom, then Settings, then Add Account.
Select Outlook.com or Office 365 from the list of account types. Enter your full email address and tap Next. Enter your password and tap Sign In. If you have two-factor authentication enabled, you will receive a code on your phone — enter it to complete the setup.
The app will sync your mail, calendar, and contacts. On first sync, downloading all your messages may take several minutes depending on how much email you have. You can start using the app while it syncs in the background.
What to do if automatic setup fails
If you see an error message during setup, the most common cause is an incorrect password. Double-check that you are typing the password correctly — passwords are case-sensitive, and spaces or extra characters will cause the login to fail. If you are not sure of your password, go to account.microsoft.com, select Sign In, and use the "Can't access your account" link to reset it.
Two-factor authentication can also block setup if the code expires or if you do not enter it in time. If you receive a code but the app times out before you enter it, start the setup process again and enter the code as soon as it arrives.
If you are using a work or school Microsoft 365 account, your organization may have additional security rules that prevent standard setup. Contact your IT department or help desk — they may need to enable the account for app access or provide you with an app password instead of your regular password.
Syncing multiple Outlook accounts in one app
You can add more than one Outlook account to the same Outlook app. Repeat the Add Account process for each email address you want to use. Each account will appear as a separate folder in your inbox list, and you can switch between them by tapping or clicking the account name.
If you also have Gmail, Yahoo, or another non-Microsoft email account, you can add those too, but they require manual server setup rather than automatic connection. The Outlook app will ask for your incoming and outgoing mail server addresses, which you can find on your email provider's website.
Frequently Asked Questions
Do I need a Microsoft account to use Outlook?
If you are adding an Outlook.com, Hotmail, or Microsoft 365 email address, you already have a Microsoft account — that email address is your account. If you are using a work or school account, your organization manages it, but you still sign in with Microsoft credentials.
What is the difference between Outlook.com and Hotmail?
Hotmail is the older name for the same service. Microsoft rebranded it to Outlook.com around 2012, but old Hotmail addresses still work. Both use the same login system and connect to Outlook the same way.
Can I add an Outlook account to Gmail or Apple Mail instead?
Yes, but it requires manual setup. You will need to generate an app password from your Microsoft account settings rather than using your regular password. Gmail and Apple Mail can then connect using that app password and Microsoft's mail servers.
Why does Outlook keep asking me to sign in again?
This usually means your password has changed or your session expired. Re-enter your current Microsoft password. If it keeps happening, check that you do not have conflicting passwords saved in your browser or password manager — delete the old one and let Outlook save the new one.
Will adding Outlook to the app delete my email from the web version?
No. Adding your account to the Outlook app does not change anything on Outlook.com or in the web version. Your email stays in the same place, and the app straightforward downloads a copy to your device so you can read it offline.
