Issue Adding Gmail Account to Outlook(on my browser): Stuck in Authentication Loop

Question

Hello Microsoft Support,

I am experiencing a recurring issue when attempting to add my Gmail account to Outlook(on browser). During the setup process, I am caught in an authentication loop that I cannot exit. Here's what happens:

1. The process begins with a prompt to "Choose an account," where I select my Gmail address.
2. I am then asked to "Sign in to Microsoft apps and services," and I click "Continue."
3. Following that, a message states "Microsoft apps & services wants to access your Google Account." I select "Allow."
4. After allowing access, I am redirected back to the initial "Choose an account" screen, and the loop starts again.

I have tried clearing my browser cache and using different browsers, but the issue persists. Could you please assist me in resolving this so I can successfully integrate my Gmail with Outlook?

Thank you for your help.

Best regards,

Larry

Hi, thank you for reaching out. My name is Deeksha and I'm a Microsoft user like yourself and I will try to help you as best as I can today.

Step 1: Clear Browser Cache and Cookies You've mentioned trying this, but it's good to ensure it's done thoroughly: Clear Cache and Cookies: In your browser, access the settings to clear browsing data. Make sure to select both "Cookies and other site data" and "Cached images and files." Restart Browser: Close your browser completely and reopen it.

Step 2: Use Incognito/Private Mode Using an incognito or private browsing session can sometimes bypass issues caused by extensions or cached data: Open Incognito Window: In your browser, open a new incognito or private window. Attempt to Add Gmail Account: Go to the Outlook on the web and try adding your Gmail account again.

Step 3: Disable Browser Extensions Sometimes browser extensions can interfere with authentication processes: Disable Extensions: Disable all browser extensions that could potentially block scripts or modify web requests (like ad blockers, security extensions, etc.). Retry Adding Account: With extensions disabled, try to add your Gmail account again.

Step 4: Check Google Account Permissions Check Google Security Settings: Go to your Google Account security settings (Google Account Security). Connected Apps: Look for the section labeled "Third-party apps with account access" and check if Microsoft apps are listed. Manage Apps: If you see Microsoft listed, try removing it. This will force the permission process to start fresh next time you attempt to link your accounts. Retry Setup: Go back to Outlook and try adding the Gmail account again.

Step 5: Try a Different Network Switch Networks: If possible, try connecting to a different network. Some network configurations, especially in corporate or public settings, might block or restrict the authentication flows. Retry Adding Account: With a different network connection, try adding your Gmail account again.

Step 6: Check for Known IssuesVisit Microsoft Office 365 Admin Center to check if there are any ongoing issues with Outlook services. Google Support: Check Google's support to see if there are any notifications about issues with third-party integrations.

Step 7: Contact Support If none of these steps resolve the issue: Microsoft Support: They can provide more specific guidance and possibly identify issues with your specific account. Google Support: Considering this involves access permissions to your Google account, it may also be helpful to contact Google support.

Try these steps and hopefully, it resolves your issue. In case you need further help or assistance, please let us know. You can also contact Microsoft Support if the problem persists.

Best regards Deeksha
