What Microsoft says
User blocked due to risk on home tenant.
How to fix it
Microsoft doesn't publish a specific fix for this code beyond the description above. This site groups it under accounts, passwords and sessions, based on that description, so start with the steps below.
How to investigate
- Confirm which account the user actually signed in with. A personal account or the wrong tenant causes many of these.
- Check the user object: enabled, licensed, in the right tenant, and with no recent password change or reset.
- Look at the sign-in logs over a few days for a pattern, such as repeated failures from one IP address.
- Search the sign-in logs for the request ID or correlation ID from the troubleshooting details on the error page.
