    Hi Linda Edwards,

    Welcome to Microsoft Q&A forum. 

    To narrow down the behavior where signing in with a PIN succeeds but the Inbox won’t open (the blue envelope icon / browser address bar keeps flickering), please help confirm the following:

    • Are you using Outlook.com (personal account) or Outlook on the web for work/school? Please also share the exact URL you’re using.
    • Which browser are you using (Edge/Chrome/Firefox/Safari)? Also, please try signing in using an InPrivate/Incognito window and temporarily disable extensions/add-ons (especially adblock/privacy ones), then share the result.
    • If you try on a different device or a different network (Wi‑Fi/4G), does the same behavior happen?

    Once these details are available, the next appropriate troubleshooting steps can be provided.

    The flickering blue envelope and address bar indicate a sign‑in/session problem with Outlook.com in the browser, not the PIN itself.

    Try these steps in order:

    1. Test in a private/incognito window
      • Open the browser’s InPrivate/Incognito window.
      • Go to Outlook.com and sign in again.
      • If the inbox opens normally there, the issue is likely cookies, cache, or an extension.
    2. Disable extensions and reset browser settings
      • Temporarily disable all browser extensions/add‑ons (especially ad‑blockers, privacy or security extensions).
      • Try Outlook.com again.
      • If it works, re‑enable extensions one by one to find the culprit.
      • If it still fails, reset the browser settings to default and retry.
    3. Clear cache and cookies for Outlook.com
      • In the browser settings, clear cached images/files and cookies for outlook.live.com / outlook.com.
      • Close all browser windows, reopen, and sign in again.
    4. Check network and try another browser/device
      • If all devices on the same network show the same flicker in the same browser, check router/firewall or security software that might be filtering Microsoft sites.
      • Try another browser (Edge/Chrome/Firefox) or another device to confirm whether the problem is browser‑specific.
    5. Use the Outlook.com support channel if still stuck
      • If sign‑in works but the inbox still never loads, use Outlook.com’s built‑in help:
        • Select Help on the Outlook.com menu bar and enter the issue.
        • If self‑help does not solve it, scroll to Still need help? and select Yes to contact support.
      • If sign‑in itself fails, use the account troubleshooter from the Outlook.com sign‑in help article.
