Hi there! I understand you’re having trouble accessing your Network Rail Viva Engage account. To help out properly, could you tell me a bit more about what happens when you try to log in? For example, do you see any error messages, does the login page not load, or does it get stuck in a loop?

Meanwhile, here are some initial steps that might help:

1. Clear browser cache and cookies: Since you're using a WebKit-based browser on Windows 10, clearing these can resolve many login-related issues.
- In your browser settings, find options for clearing browsing data.
- Make sure to clear cookies and cached files.

2. Check your internet connection: Make sure your network connection is stable.

3. Try signing in via a different browser or an incognito/private window: This can help determine if the issue is browser-specific.

4. Verify credentials and account status: Double-check that your Network Rail Viva Engage account credentials are correct. If you suspect your account might be locked or disabled, you may need to contact your IT administrator for Network Rail.

5. Update browser and system components: Even though you’re on Windows 10, sometimes underlying components like WebView or browser updates can affect access. Ensure your browser is up to date.

If after these steps the issue persists, it might be related to specific session or tenant access issues. If you’re attempting to access as a guest or using a specific tenant setup, resetting the app session or credentials is advised (common in mobile apps, but if a web session is involved, signing out completely and signing back in sometimes helps).

Could you also let me know if you have access to other Microsoft 365 services with your Network Rail account or if this issue is only with Viva Engage? That way, I can tailor the next steps better.

Looking forward to your reply so we can get you back connected!
