How to Add an Email Account to Outlook (Every Version, 2026)

OutlookEmail SetupMicrosoft 365GmailHow-toImapExchange

Adding an email account to Outlook is usually a two-minute job, but the exact steps depend on which version of Outlook you’re using and what kind of account you’re connecting. The new Outlook for Windows (now the default on Windows 11) uses cloud-based account setup that mirrors Outlook on the web. Classic Outlook for Windows still has the older Add Account wizard with manual IMAP and POP options. And some providers — Gmail, Yahoo, iCloud — require you to authenticate through their own login flow or generate an app password.

Here’s how to add each account type in each version.

1. New Outlook for Windows

The new Outlook is now the default mail app on Windows 11 and ships with a simplified, cloud-first setup flow. Microsoft 365, Outlook.com, Gmail, Yahoo, and iCloud all connect through OAuth — you sign in to the provider directly and Outlook stores a token instead of your password.

Add a Microsoft 365 or Outlook.com account

  1. Open new Outlook.
  2. Click the Settings gear in the top-right.
  3. Go to Accounts > Email accounts.
  4. Click Add account.
  5. Type your email address and click Continue.
  6. Enter your password (or approve through Microsoft Authenticator if you use 2FA).
  7. Click Done. The account appears in the left folder pane and starts syncing.

Add a Gmail account

  1. Click Settings > Accounts > Email accounts > Add account.
  2. Type your Gmail address and click Continue.
  3. New Outlook redirects you to Google’s sign-in page. Enter your Google password.
  4. Approve the Microsoft apps & services consent screen — this gives Outlook permission to read, send, and organize mail.
  5. Click Done when redirected back.

Note: If you have advanced Google Workspace policies that block third-party access, your admin will need to enable Microsoft Outlook in the Google Workspace admin console.

Add a Yahoo or iCloud account

The flow is identical to Gmail — type the address, sign in to Yahoo or Apple’s auth page, and approve access. iCloud accounts with two-factor authentication require an app-specific password generated at account.apple.com.

Add an IMAP/POP account

New Outlook supports IMAP for any provider that publishes server details. POP is supported but limited.

  1. Click Settings > Accounts > Email accounts > Add account.
  2. Enter the email address and click Continue.
  3. If autodiscover fails, click Advanced setup > IMAP.
  4. Enter the incoming server (e.g., imap.yourprovider.com, port 993, SSL/TLS).
  5. Enter the outgoing server (e.g., smtp.yourprovider.com, port 587, STARTTLS).
  6. Enter your password and click Continue.

2. Classic Outlook for Windows

Classic Outlook is still supported and remains the only desktop option for some Exchange on-premises and PST-based workflows. Setup is done from the File menu.

Add any account through autodiscover

  1. Open classic Outlook.
  2. Click File > Info > Add Account.
  3. Type your email address.
  4. Click Connect.
  5. Outlook attempts to detect the account type. For Microsoft 365, Outlook.com, and most Gmail/Yahoo accounts, you’ll be redirected to a sign-in window — enter your password and approve.
  6. Click Done.

Add an Exchange or Microsoft 365 account manually

If autodiscover fails (common on hybrid Exchange setups), set it up manually:

  1. File > Add Account > type the address > Advanced options > check Let me set up my account manually > Connect.
  2. Choose Exchange or Microsoft 365.
  3. Enter your password when prompted.
  4. If you’re on Exchange on-premises, your IT team may need to provide the server name and configure autodiscover DNS records.

Add an IMAP or POP account manually

  1. File > Add Account > type the address > Advanced options > check Let me set up my account manually > Connect.
  2. Choose IMAP or POP.
  3. Enter the Incoming mail server, Outgoing mail server (SMTP), ports, and encryption methods from your provider.
  4. Click Next, enter the password, and click Done.

Common server settings:

ProviderIMAP serverIMAP portSMTP serverSMTP port
Gmailimap.gmail.com993 (SSL)smtp.gmail.com587 (STARTTLS)
Outlook.comoutlook.office365.com993 (SSL)smtp.office365.com587 (STARTTLS)
Yahooimap.mail.yahoo.com993 (SSL)smtp.mail.yahoo.com587 (STARTTLS) or 465 (SSL)
iCloudimap.mail.me.com993 (SSL)smtp.mail.me.com587 (STARTTLS)

Tip: If Outlook keeps prompting for a password and your account uses 2FA, you almost certainly need an app password — see section 5 below.

3. Outlook on the Web

Outlook on the web doesn’t run as a desktop app, so “adding an account” usually means connecting another mailbox to your primary Outlook.com or Microsoft 365 inbox.

Connect another email account

  1. Sign in at outlook.office.com or outlook.live.com.
  2. Click the Settings gear in the top-right.
  3. Go to Mail > Sync email.
  4. Under Connected accounts, click Other email accounts.
  5. Enter the display name, email address, and password for the account you want to connect.
  6. Click OK. Outlook starts importing messages via POP.

This is one-way sync (incoming only) and works best for consolidating personal Gmail or Yahoo accounts into a single Outlook inbox. To send mail from the connected address, add it as a send-from alias under Mail > Sync email > Send mail from another address.

Switch between work and personal Microsoft accounts

If you want to view a second Microsoft account in the web app, click your profile picture in the top-right and choose Open another mailbox or Add account. Each account opens in a separate browser tab.

4. Outlook for Mac

The Mac version (now part of the unified “new Outlook” rollout) uses the same OAuth flow as new Outlook for Windows.

  1. Open Outlook.
  2. Click Outlook > Settings > Accounts.
  3. Click the + button > Add Email Account.
  4. Type the email address and click Continue.
  5. Sign in to the provider’s authentication window.
  6. Click Done.

For IMAP/POP, click Not [provider]? on the sign-in screen, choose IMAP/POP, and enter the server details manually.

5. Common Errors and How to Fix Them

”Something went wrong” or password keeps getting rejected

Almost always a 2FA problem. Generate an app password:

  • Gmail: myaccount.google.com > Security > 2-Step Verification > App passwords. Create one for “Mail” / “Windows Computer” and use the 16-character password instead of your Google password.
  • Yahoo: login.yahoo.com > Account security > Generate app password.
  • iCloud: account.apple.com > Sign-In and Security > App-Specific Passwords > Generate Password.

”Account couldn’t be set up” / autodiscover fails

This happens with custom domains, Exchange on-premises, or misconfigured DNS. Set the account up manually as IMAP and ask your IT admin to fix the autodiscover record (autodiscover.yourdomain.com should point to the mail provider).

Gmail account added but folders are missing

Gmail labels don’t map cleanly to Outlook folders. In Gmail, go to Settings > Labels and make sure Show in IMAP is enabled for any labels you want to see in Outlook. The All Mail label in particular should be visible.

Calendar or contacts not syncing for an IMAP account

IMAP only syncs mail. For calendar and contacts you need Exchange ActiveSync (Microsoft 365, Outlook.com) or a CalDAV/CardDAV-compatible setup. Gmail calendar and contacts won’t appear in Outlook unless you connect through Microsoft 365’s third-party Gmail connector or use the Google Workspace Sync for Microsoft Outlook plug-in.

”Outlook is offline” after adding an account

Click Send/Receive > Work Offline to toggle online mode. If that doesn’t work, restart Outlook and run File > Account Settings > Repair.

Old account stuck after removing it

Go to Settings > Accounts > Email accounts, click the account, and choose Remove. In classic Outlook, also check Control Panel > Mail > Show Profiles for orphaned profiles.
