    Dear @Yvonne Lau OTTE ,

    I understand that after signing in to Microsoft Online, you are seeing a blank screen in your web browser and are unable to access Microsoft 365 services such as SharePoint.

    I recommend some steps below:

    1/ Try an InPrivate/Incognito browser session

    • Open your browser’s InPrivate or Incognito window
    • Sign in again at https://www.office.com .If it works in this mode, the issue is likely related to browser cache or extensions.

    2/ Clear browser cache and cookies

    Please clear your browser cache and cookies, then restart the browser. Focus on cookies and data related to: login.microsoftonline.com, office.com. sharepoint.com

    3/ Disable browser extensions

    Some browser extensions (such as ad blockers, privacy tools, or security add‑ins) can block required Microsoft scripts.

    • Temporarily disable all extensions
    • Restart the browser and test again If this resolves the issue, re‑enable extensions one by one to identify the cause.

    4/ Update or switch browser

    Ensure you are using a supported and up-to-date browser

    5/ Check Network or VPN

    If you are connected to a VPN, proxy, or corporate firewall: Temporarily disconnect from the VPN, Try accessing Microsoft 365 from a different network (for example, a home network or mobile hotspot)

    If the issue continues, please provide the following details so we can investigate further:

    • Does the issue occur in an InPrivate / Incognito browser window?
    • Which browser and version are you using? (Edge, Chrome, Firefox, etc.)
    • Does the issue happen on more than one browser?
    • Are you using any of the following extensions? Ad blocker, Privacy or script‑blocking tool, Antivirus or endpoint security add‑in
    • Does the issue occur on a different device or network? (for example, home network vs. office network)
    • Are you connected to a VPN or corporate proxy?
    • Does the blank screen appear immediately after sign‑in, or after selecting SharePoint or another app?
    • Could you please share the screenshot of the blank screen (showing the browser address bar)

    Please understand that the initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.        

    Your detailed response will help us diagnose and investigate the issue more efficiently. If I misunderstood what you’re looking for, feel free to let me know or share a screenshot. I’d be happy to help further!

    Thank you for your cooperation. I'm looking forward for your reply.

    Try these steps to troubleshoot a blank screen after signing in, focusing on Windows and browser display issues:

    1. Basic display checks
    • Make sure the device is powered, charged, and any external monitor is turned on and connected firmly (HDMI/DisplayPort/VGA).
    • If using multiple displays, disconnect external monitors temporarily and test with only the main screen.
    1. Wake or reset the graphics
    • Press Windows + Ctrl + Shift + B once. The screen should briefly flicker or a beep may be heard, which resets the graphics driver.
    1. Check display mode
    • Press Windows + P, then press P again and Enter to cycle display modes (PC screen only / Duplicate / Extend). Repeat a few times in case Windows is sending output to a non‑existent display.
    1. Test Windows shell
    • Press Ctrl + Alt + Del.
      • If the security screen appears, select Task Manager.
      • In Task Manager, find Windows Explorer, right‑click and choose Restart.
      • If Windows Explorer is missing, select File > Run new task, type explorer.exe, press Enter.
    1. Force restart
    • Hold the power button for about 20 seconds to turn the device off.
    • Turn it back on and sign in again, then test the browser.
    1. Advanced steps if the screen stays blank
    • Force shutdown by holding the power button for 10 seconds.
    • Repeat this 2–3 times until Windows Recovery appears.
    • Go to Troubleshoot > Advanced options > Startup Settings > Restart.
    • Press F5 for Safe Mode with Networking.
    • In Safe Mode:
      • Open Device Manager → expand Display adapters → right‑click the GPU → Update driver. If the problem started after a driver update, use Roll back driver instead.
      • Restart normally and test sign‑in and browser again.

    If the issue is only inside the browser after sign‑in (and Windows itself is fine), also test with another browser and a different Windows user profile to rule out profile‑specific or browser‑specific problems.
