How to unblock your account
If you are attempting to sign-in to another organization as a guest and are blocked due to risk, you will see the following block message: "Your account is blocked. We've detected suspicious activity on your account" or "Your account has been locked. Contact yoru support person to unlock it, then try again".
If your organization enables it, you can use self-service password reset unblock your account and get your credentials back to a safe state.
- Go to the Password reset portal and initiate the password reset. If self-service password reset is not enabled for your account and you cannot proceed, reach out to your IT administrator with the information below.
- If self-service password reset is enabled for your account, you will be prompted to verify your identity using security methods prior to changing your password. For assistance, see the Reset your work or school password article.
- Once you have successfully and securely reset your password, your user risk will be remediated. You can now try again to sign-in as a guest user.
If after resetting your password you are still blocked as a guest due to risk, reach out to your organization's IT administrator.
How to remediate a user's risk as an administrator (Users home tenant)
Identity Protection automatically detects risky users for Azure AD tenants. If you have not previously checked the Identity Protection reports, there may be a large number of users with risk. Since resource tenants can apply user risk policies to guest users, your users can be blocked due to risk even if they were previously unaware of their risky state. If your user reports they have been blocked as a guest user in another tenant due to risk, it is important to remediate the user to protect their account and enable collaboration.
Reset the user's password
From the Risky users report in the Azure AD Security menu, search for the impacted user using the 'User' filter. Select the impacted user in the report and click "Reset password" in the top toolbar. The user will be assigned a temporary password that must be changed on the next sign in. This process will remediate their user risk and bring their credentials back to a safe state.
Manually dismiss user's risk
If password reset is not an option for you from the Azure AD portal, you can choose to manually dismiss user risk. This process will cause the user to no longer be at risk, but does not have any impact on the existing password. It is important that you change the user's password using whatever means are available to you in order to bring the identity back to a safe state.
To dismiss user risk, go to the Risky users report in the Azure AD Security menu. Search for the impacted user using the 'User' filter and click on the user. Click on "dismiss user risk" option from the top toolbar. This action may take a few minutes to complete and update the user risk state in the report.
