How to Set Up Email on Windows — New Outlook and Mail App Guide (2026)
Step-by-step guide to setting up email on Windows 10 and 11. Covers the new Outlook app, classic Outlook, Gmail, Yahoo, IMAP accounts, multiple inboxes, and fixes for common setup problems.
Setting up email on Windows used to be simple and has recently become slightly more complicated — not because it got harder, but because Microsoft has been transitioning from the legacy Mail and Calendar apps to a unified new Outlook experience, and the terminology across app names, versions, and Microsoft's own documentation has not always kept pace with the product changes. This guide cuts through that and covers how to set up email on Windows 10 and 11 across every current scenario: new Outlook, classic Outlook, Gmail, business email, IMAP accounts, and multiple inboxes — with plain steps and the troubleshooting fixes you actually need.
First: which email app do you have?
The setup steps differ depending on which Outlook version is installed. Here is how to tell them apart and which one to use.
New Outlook for Windows
- Ships with Windows 11 (23H2 and later)
- Free — no Microsoft 365 subscription required
- Modern interface, nearly identical to Outlook on the web
- Supports Microsoft, Gmail, Yahoo, iCloud, IMAP
- Cloud-synced — emails stored on Microsoft servers
- Best for: home users, light business use
Classic Outlook for Windows
- Part of Microsoft 365 Personal/Family/Business
- Full PST file support, offline access
- Mail merge, shared calendars, delegate access
- More configuration options, heavier footprint
- Best for: organisations, power users, offline-heavy workflows
The classic Windows Mail and Calendar apps that shipped with Windows 10 have been officially replaced by new Outlook as the default email client on Windows 11. If you are still using the legacy Mail app, you will see a Try the new Outlook toggle in the upper right corner — clicking it downloads new Outlook and migrates your existing accounts automatically. Microsoft has confirmed the legacy Mail app will eventually be fully retired.
Setting up new Outlook for Windows
Adding your first account
Microsoft, Outlook.com, or Hotmail account
- Open Outlook from the Start menu. On Windows 11 (23H2+) it is pre-installed. If not present, search for it in the Microsoft Store and install it free.
- On first launch, Outlook will prompt you to add an account. If your Windows account is a Microsoft account (Outlook.com, Hotmail, or Live), it will appear automatically — click it to proceed.
- If not prompted automatically, click the gear icon (Settings) in the top right, then Add account.
- Enter your email address and click Continue.
- Sign in with your Microsoft account password. Outlook will configure everything automatically.
- Your inbox will begin syncing within a few minutes depending on how many emails you have.
Adding a Gmail account to new Outlook
- Click the gear icon (Settings) in the top right of Outlook.
- Click Add account.
- Enter your Gmail address and click Continue.
- Outlook will open Google's sign-in page — enter your Gmail password and complete any two-factor authentication steps.
- Google will ask you to grant Outlook permission to access your Gmail — click Allow.
- Your Gmail inbox will sync to Outlook. Gmail folders appear in the left sidebar beneath your account name.
When you add Gmail to new Outlook, Microsoft routes your Gmail through its own servers to enable sync. A dialog box will inform you of this and ask you to agree before setup continues. If you prefer your Gmail not to pass through Microsoft infrastructure, use the Gmail web interface at gmail.com, or add Gmail to classic Outlook via IMAP (which routes directly between your PC and Google's servers).
Adding Yahoo, iCloud, or other email accounts
- Click the gear icon > Add account.
- Enter your email address and click Continue.
- For Yahoo and iCloud, Outlook will recognise the provider and open the relevant sign-in page. Complete authentication there.
- For Yahoo accounts with two-step verification: you will need to generate an App Password in your Yahoo account security settings and use that instead of your normal Yahoo password.
- For iCloud: generate an App-Specific Password at appleid.apple.com under Security. Use that as your password in Outlook setup.
Setting up classic Outlook for Windows
First account setup in classic Outlook
- Open Outlook (the classic desktop application, identified by the blue and white icon with a full toolbar).
- On first launch, the account setup wizard appears automatically. Enter your email address and click Connect.
- For Microsoft 365 work or school accounts, Outlook detects the account type and signs you in via your organisation's login page.
- For personal Microsoft accounts (Outlook.com, Hotmail), enter your password when prompted.
- Click Done when setup completes. Your mail, calendar, and contacts will begin syncing.
Adding additional accounts in classic Outlook
- Click File in the top left.
- Click Add Account.
- Enter the email address and click Connect. Classic Outlook automatically detects most major providers (Microsoft, Gmail, Yahoo) and configures the connection. For Gmail, enable IMAP in Gmail settings first (Gmail > Settings > See all settings > Forwarding and POP/IMAP > Enable IMAP).
- Sign in when prompted. The new account appears in the left sidebar alongside your existing accounts.
Setting up a business or custom domain email
If your business uses a custom domain email address (yourname@yourbusiness.com) hosted on a non-Microsoft server — such as GoDaddy, Bluehost, Google Workspace, or another hosting provider — you will need the IMAP or POP settings from your email host. These are typically found in your hosting control panel under Email Settings or Email Configuration.
| Setting | Where to find it | Common example values |
|---|---|---|
| Incoming mail server (IMAP) | Hosting control panel > Email settings | mail.yourdomain.com or imap.yourdomain.com |
| Incoming port | Same location | 993 (IMAP with SSL) — always use SSL |
| Outgoing mail server (SMTP) | Same location | mail.yourdomain.com or smtp.yourdomain.com |
| Outgoing port | Same location | 465 (SSL) or 587 (TLS) |
| Username | Usually your full email address | yourname@yourdomain.com |
| Password | Your email account password (set in hosting panel) | — |
Manual IMAP setup in new Outlook
- Click the gear icon > Add account.
- Enter your business email address and click Continue.
- If Outlook does not recognise the provider automatically, click Advanced options and check Let me set up my account manually.
- Select IMAP.
- Enter the incoming and outgoing server settings from your hosting panel.
- Click Continue, enter your password, and let Outlook test the connection.
Manual IMAP setup in classic Outlook
- Go to File > Add Account.
- Enter your email address and click Advanced options > Let me set up my account manually > Connect.
- Select IMAP.
- Enter the server details. Make sure SSL/TLS is selected for both incoming and outgoing settings.
- Click Next, enter your password, and click Connect.
Adding multiple email accounts
Both new Outlook and classic Outlook support multiple email accounts in the same inbox. Each account appears as a separate entry in the left sidebar with its own folder hierarchy. You can set which account is used by default when composing a new email: in new Outlook, go to Settings > Accounts > Your accounts and set the default. In classic Outlook, go to File > Account Settings > Account Settings, select an account, and click Set as Default.
New Outlook enables Focused Inbox by default — it separates mail it thinks is important into the Focused tab and everything else into Other. If emails are going missing or you prefer to see everything in one place, go to View > Show Focused Inbox to toggle it off. This is one of the first things worth changing if your inbox feels incomplete after setup.

Frequently asked questions
What is the difference between new Outlook and classic Outlook?
New Outlook ships free with Windows 11 (23H2+) and supports Microsoft, Gmail, Yahoo, iCloud, and IMAP accounts. It is cloud-first and nearly identical to the Outlook web interface. Classic Outlook is included with Microsoft 365 subscriptions and adds PST file support, full offline access, mail merge, and advanced organisational features. For most home users, new Outlook is sufficient. For complex business workflows, classic Outlook is the better choice.
Can I add Gmail to Outlook on Windows?
Yes. In new Outlook, click Settings (gear icon) > Add account, enter your Gmail address, and sign in through Google's authentication. In classic Outlook, go to File > Add Account, enter your Gmail address, and enable IMAP in Gmail settings first (Gmail > Settings > Forwarding and POP/IMAP > Enable IMAP). If using two-factor authentication, use an App Password rather than your regular Gmail password.
How do I set up a business email account in Outlook?
Microsoft 365 business accounts configure automatically — just enter your work email address and sign in. For custom domain email (yourname@yourbusiness.com) on another host, you need the IMAP/SMTP server settings from your hosting control panel: incoming server, port 993 (SSL), outgoing server, port 587 (TLS), and your email credentials. Enter these in Outlook's manual IMAP setup option.
Why is Outlook not receiving emails after setup?
Most common causes: IMAP not enabled in the source account (Gmail and Yahoo require this), incorrect server settings, or a regular password being rejected because two-factor authentication requires an App Password. Check IMAP is enabled in the source account's settings, verify server details are correct, and generate an App Password if two-factor authentication is active.
Is the Windows Mail app still available in 2026?
The legacy Windows Mail and Calendar apps have been replaced by new Outlook as the default email client on Windows 11. If you still have the legacy Mail app, a Try the new Outlook toggle appears in the upper right — clicking it downloads new Outlook and migrates your accounts automatically.
