Hi @Ashish Mandal,
You may have the group policy BrowserSignin set to Disable browser sign-in, so the browser won't allow you to sign in.
To re-enable sign-in, you should un-configure this policy. Follow the steps:
- Navigate to edge://policy in Microsoft Edge and check if you actually have this policy configured like this:
- If you have this policy, then you should go to registry editor to remove this policy. Open Run by Win+R, input regedit, and hit OK.
- In Registry Editor, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge and HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge. You should find if you have BrowserSignin key. Delete the key if any.
- Restart Microsoft Edge.
Now you should be able to sign in again.
Please note that group policy is usually configured by your Admin. If you are unable to remove this key, or you wonder why you have this policy configured, please contact your Admin for more information.
