microsoft sign in

Question

I'm trying to sign into an app and it tells me sign in successful will redirect (to that app) in a moment. then nothing happens.

Answer 1

Hi, I'm John! I will help you with this.

To help narrow down the issue:

1. Which app are you trying to sign into? (Teams, Outlook, OneDrive, or something else?)
2. Are you signing in through a browser or inside the app itself?
3. Which browser are you using, if any?
4. Does anything pop up (like a blank page or loading screen), or it just stays there?

Answer 2

The sign-in is completing, but the redirect back to the app is failing. This is typically caused by browser or cookie issues, or by how the app’s sign-in flow is configured.

Try these steps in order:

1. Check the sign-in actually worked
   • Go to https://www.office.com and select Sign in.
   • If sign-in succeeds there and shows the correct account in the header, the account itself is fine.
2. Clear browser cache and cookies, then retry
   • Clear cookies and cache for microsoft.com, login.live.com, and login.microsoftonline.com.
   • Close all browser windows, reopen, and try signing into the app again.
3. Check browser security / trusted sites settings (Windows)
   If using Internet Explorer or Microsoft Edge and you see a loop or no redirect:
   • Open Internet Options → Security → Trusted sites.
   • Make sure these are not in Trusted sites, or if policy requires them there, ensure all of them are present so cookies can be shared:
     1. microsoft.com
     2. support.microsoft.com and any subdomains used
     3. login.live.com
     4. login.microsoftonline.com
   • Apply changes, close the browser, and try again.
4. Try a different browser or device
   • If the app uses the system browser for sign-in, try another browser (for example, if using Edge, try Chrome or Firefox) and sign in again.
   • If it works elsewhere, the issue is with the original browser’s cookies or security zone configuration.
5. If the app is a web app using Microsoft sign-in
   The app relies on a redirect URI registered with Microsoft Entra ID. If the app never loads after “sign in successful,” the redirect URI might not match what is registered. In that case, contact the app’s support so they can verify the redirect URI configuration in their Microsoft Entra application.

If none of these steps help and the issue is specifically with Microsoft’s own portals (like My Apps), verify the site address is correct (https://myapps.microsoft.com or your organization’s custom URL), ensure the password is valid and not expired, and clear the browser cache before trying again.
