Fix: Outlook Keeps Asking for Gmail Password (Google Workspace App Password Solution)

Posted on 03-11-2025 | Category: General | Views: 31


If your Outlook keeps asking for your Gmail or Google Workspace password, even after enabling POP and creating an App Password, you’re not alone. Thousands of professionals face this frustrating loop — especially after Google enforced 2-Step Verification and enhanced authentication protocols.

In this guide, we’ll cover exactly why this happens and walk you through detailed step-by-step solutions that work for both individual Gmail users and Google Workspace accounts.


? Why Outlook Keeps Asking for Password

Outlook uses older POP/IMAP protocols to connect to email servers.
When Google upgraded its security model (requiring OAuth2 or App Passwords), older Outlook configurations broke because:

  • They tried authenticating using your normal Gmail password, not the app password.

  • POP access wasn’t fully enabled in Gmail settings or in the Workspace Admin Console.

  • The security check blocked “less secure apps.”

  • Ports or encryption mismatches existed (e.g., TLS vs SSL).

As a result, Outlook can’t authenticate and keeps prompting for a password.


✅ Step-by-Step Fix Guide

Step 1: Enable POP in Gmail Settings

  1. Log in to Gmail (same Google Workspace email).

  2. Click the ⚙️ Settings → See all settings → Forwarding and POP/IMAP.

  3. Under POP Download:

    • Select Enable POP for all mail (or “Enable POP for mail that arrives from now on”).

    • Choose Keep Gmail’s copy in the Inbox.

  4. Click Save Changes.


Step 2: Create an App Password

If you have 2-Step Verification enabled, a normal password won’t work anymore.

  1. Visit https://myaccount.google.com/apppasswords

  2. Re-enter your password to verify.

  3. Choose:

    • App: Mail

    • Device: Windows Computer

  4. Click Generate.

  5. Copy the 16-character app password (no spaces).

? Important: This password replaces your regular Gmail password when setting up Outlook.


Step 3: Configure Outlook Correctly

Open Outlook → File → Account Settings → Add New Account → Manual Setup / POP or IMAP

Incoming Mail (POP3):

  • Server: pop.gmail.com

  • Port: 995

  • Encryption: SSL/TLS

Outgoing Mail (SMTP):

  • Server: smtp.gmail.com

  • Port: 465 (SSL) or 587 (STARTTLS)

  • Encryption: SSL/TLS

  • Requires authentication ✅

  • Use same login credentials as incoming mail ✅

Login Information:

  • Username: your full email (e.g., user@yourdomain.com)

  • Password: the App Password you generated earlier

Uncheck “Require logon using Secure Password Authentication (SPA)” — this causes authentication errors with Gmail.


Step 4: Check Google Workspace Admin Console

If you’re using Google Workspace, the administrator must enable POP access:

  1. Go to admin.google.comApps → Google Workspace → Gmail → User Settings.

  2. Scroll down to POP and IMAP Access.

  3. Ensure:

    • Enable POP access for all users

    • ✅ “Allow users to configure mail clients”

  4. Save changes.

  5. Wait 15–30 minutes for settings to propagate.


Step 5: Allow Google Security Access

Sometimes Google blocks Outlook’s connection as “suspicious.”

  1. Visit https://myaccount.google.com/security-checkup

  2. Review any blocked sign-in attempts.

  3. Click Yes, that was me / Allow access if Outlook is being blocked.

Then restart Outlook and try again.


Step 6: Clear Old Credentials in Windows

Sometimes cached credentials cause the loop.

  1. Go to Control Panel → Credential Manager → Windows Credentials.

  2. Look for entries like mail.google.com or your email address.

  3. Remove them.

  4. Restart Outlook and re-enter the App Password.


Step 7: Test POP Connection

To ensure the POP service is active:

  • Visit https://pop.gmail.com
    If it shows a secure certificate and no “Access Denied” message, POP is working.

If blocked, contact your Workspace admin.


⚡ Common Mistakes and Their Fixes

ProblemSolution
Using normal passwordAlways use App Password
POP not enabledEnable in Gmail Settings
Wrong ports995 (POP), 465/587 (SMTP)
“Less secure app” settingUse App Password instead
SPA checked in OutlookUncheck “Secure Password Authentication”
Cached old credentialsRemove via Windows Credential Manager


? Expert Tips

  • Prefer IMAP over POP if possible — IMAP syncs all folders and is more modern.

  • Always use App Passwords for any non-Google client (Outlook, Thunderbird, etc.).

  • Avoid using “Less secure app access” — Google has discontinued it since 2022.

  • Check Workspace Audit Logs if users still fail to authenticate.

? Conclusion

Google’s security changes are meant to protect your data, but they can make traditional clients like Outlook behave unpredictably. The key is to use App Passwords, ensure POP/IMAP is properly enabled, and double-check encryption ports and admin policies.

After following this guide, your Outlook–Google Workspace connection should work flawlessly — no more password prompts!
