-- Review the user's [investigation priority score](tutorial-ueba.md#understand-the-investigation-priority-score) and compare with the rest of the organization. This will help you identify which users in your organization pose the greatest risk.
 - If you identify a **TP**, review all the user's activities to gain an understanding of the impact.

-Anomalous activities and activities that triggered alerts are given scores based on severity, user impact, and behavioral analysis of the user. The analysis is done based on other users in the tenants.
+Starting November 2024, **Investigate risky users** support for Microsoft Defender for Cloud Apps is retired. If this feature was used in your organization and is needed, we recommend using the Entra risk score feature. Please use the following resources for additional information:

-  
-    **Recommended action**: Suspend the user, mark the user as compromised, and reset their password.
-
-1. **B-TP**: If you're able to confirm that user indeed significantly deviated from usual behavior, but there's no potential breach.
-
-1. **FP**  (Unusual behavior): If you're able to confirm that the user legitimately performed the unusual activities, or more activities than the established baseline.

-#### Deprecation timeline
-
-We're gradually retiring the **Investigation priority score increase** alert from Microsoft Defender for Cloud Apps by August 2024.
-
-After careful analysis and consideration, we decided to deprecate it due to the high rate of false positives associated with this alert, which we found wasn't contributing effectively to the overall security of your organization.
-
-Our research indicated that this feature wasn't adding significant value and wasn't aligned with our strategic focus on delivering high-quality, reliable security solutions.
-
-We're committed to continuously improving our services and ensuring that they meet your needs and expectations.
-
-For those who wish to continue using this alert, we suggest using the following advanced hunting query instead as a suggested template. Modify the query based on your needs.
-
-```kql    
-let time_back = 1d;
-let last_seen_threshold = 30;
-// the number of days which the resource is considered to be in use by the user lately, and therefore not indicates anomaly resource usage
-// anomaly score based on LastSeenForUser column in CloudAppEvents table
