Add Yahoo Mail to Outlook in 2026 with updated IMAP/SMTP settings, OAuth vs app password guidance, and setup steps for New Outlook, Classic Outlook, Mac, and mobile.
Use the decision box and quick table below to pick the right login method and avoid password loops.
Quick Steps
- New Outlook: Add account → Yahoo sign-in page = OAuth.
- Classic/basic password box: Create Yahoo app password.
- Manual IMAP: Use the table settings.
- Password loop: Clear Credential Manager → new app password.
Do you see a Yahoo sign-in web page?
- Yes: You are using OAuth. Sign in with your normal Yahoo password.
- No (basic password box or repeated prompts): Use a Yahoo app password.
Official note: Outlook Desktop can support Yahoo via OAuth, so an app password is not always required.
Quick Answer (2026)
| Setting | Value |
|---|---|
| IMAP server | imap.mail.yahoo.com |
| IMAP port | 993 (SSL/TLS) |
| SMTP server | smtp.mail.yahoo.com |
| SMTP port | 465 (SSL/TLS) or 587 (STARTTLS) |
| SMTP authentication | Required |
| Username | Full Yahoo email address |
| Password | If Outlook shows the Yahoo sign-in page, use your normal password (OAuth). If Outlook shows a basic password box or keeps prompting, use a Yahoo app password. |
Tip: If sending fails on 465, try 587 with STARTTLS.
Outlook types (2026)
- New Outlook for Windows: different UI, uses a web-style sign-in and may use OAuth.
- Classic Outlook (desktop): manual IMAP setup is common and supports app passwords.
- Outlook.com (web): no longer supports adding new connected Yahoo accounts.
IMAP vs POP (quick rule)
- IMAP: two-way sync across devices. Recommended for most users.
- POP: downloads mail to one device and may remove it from the server depending on your POP settings. Use only if you need local-only storage.
Step 1: Create a Yahoo app password (if needed)
Use this only if Outlook does not show a Yahoo sign-in web page or keeps asking for a password.
- Open Yahoo Account Security.
- Go to External connections and choose Create app password (or Generate and manage app passwords).
- If you do not see Create app password, enable 2-step verification first.
- Enter an app name like Outlook and generate the password.
- Copy the 16-character app password and use it in Outlook.
Step 2: Add Yahoo to New Outlook for Windows
- Open Outlook and go to View > View settings.
- You can also click Add account at the bottom of the folder list.
- Open Accounts and click Add account.
- Enter your Yahoo email address and continue.
- If you see Advanced options, choose Let me set up my account manually and select IMAP.
- Enter the server settings and use your Yahoo app password if prompted.
Note: Username must be the full email address, and SMTP requires authentication.
Step 3: Add Yahoo to Classic Outlook (desktop)
- Go to File > Add Account.
- Enter your Yahoo email address and click Connect.
- If automatic setup fails, choose Manual setup and select IMAP.
- Incoming (IMAP): imap.mail.yahoo.com
- Outgoing (SMTP): smtp.mail.yahoo.com
- IMAP port: 993 (SSL/TLS)
- SMTP port: 465 (SSL/TLS) or 587 (STARTTLS)
- Username: full Yahoo email address
- Password: Yahoo app password (if required)
Note: Ensure My outgoing server (SMTP) requires authentication is enabled.
Step 4: Add Yahoo to Outlook for Mac
- Open Outlook for Mac and go to Tools > Accounts.
- Click + and choose New Account.
- Enter your Yahoo email address and continue.
- When prompted, enter your Yahoo app password (if required) and select IMAP.
Note: If prompted for server settings, use the same IMAP/SMTP values in the Quick Answer table.
Step 5: Add Yahoo to Outlook Mobile (iOS/Android)
- Open Outlook mobile and tap Add Account.
- Select Yahoo and sign in through the Yahoo sign-in screen.
- If manual setup appears, use IMAP with the settings above.

| Outgoing mail server | smtp.bizmail.yahoo.com |
| Port | 465 |
| Encryption method | SSL/TLS |

Troubleshooting
Fix by symptom:Password loop | Cannot send | New Outlook sync | Missing folders
Common error phrases:
- Authentication failed - reset the app password and clear cached credentials.
- Cannot connect to server - recheck IMAP/SMTP hostnames and ports.
- Your IMAP server wants to alert you... - confirm SSL/TLS and try manual IMAP.
- We could not sign you in - use the Yahoo sign-in page (OAuth) or an app password.
- 0x800CCC0E - usually server/port/security mismatch; recheck 993 SSL and 465/587.
- 0x800CCC0F - usually server/port/security mismatch; recheck 993 SSL and 465/587.
Outlook keeps asking for Yahoo password (OAuth vs app password mismatch)
Remove cached credentials: type “Credential Manager” in the Windows Start menu, open it, select Windows Credentials, and delete entries related to Outlook or your Yahoo address. If Outlook shows a basic password box, generate a new Yahoo app password and try again.
Cannot send mail (SMTP auth required / 465 vs 587)
Confirm SMTP authentication is enabled. Classic Outlook: Account Settings -> Change -> More Settings -> Outgoing Server -> check “My outgoing server requires authentication.” Try port 465 with SSL/TLS, and if it fails, use 587 with STARTTLS.
New Outlook: account add fails / stuck on sync screen
Remove cached credentials, re-add the account, and use manual IMAP if prompted. Outlook.com web no longer supports new connected Yahoo accounts.
Missing folders
Subscribe to all IMAP folders you need. Classic Outlook: right-click the mailbox -> IMAP Folders -> Query -> Subscribe. Outlook for Mac: Tools -> Accounts -> Advanced -> Server -> Folders -> Subscribe.

The Final Word
Use IMAP for Yahoo in Outlook, sign in with OAuth when available, and fall back to an app password when you see a basic password prompt. If SMTP fails on 465, try 587 with STARTTLS. For long-term storage, export Yahoo mail with a backup tool and keep a PST archive.
