In Salesforce, Lead and Case record ownership can change automatically — even when users are not logged in — due to several mechanisms: Assignment Rules, automation tools (Flows, Apex Triggers, Workflow Rules, or Process Builder), or third-party AppExchange applications that use a default user account. This article describes how to identify and troubleshoot the root cause of unexpected Lead or Case ownership changes in your Salesforce organization.
To investigate unexpected ownership changes on Lead or Case records, check the following areas in your Salesforce org:
Assignment Rules automatically reassign record ownership based on criteria you define. If an assignment rule matches a Lead or Case, Salesforce reassigns the record to the rule's designated owner. If no rule matches, Salesforce assigns the record to the default owner configured in Lead Settings or Support Settings.

Lead and Case ownership can also be changed by automation triggered when a record is created or updated, including:
Review active automations for actions that change the Owner field on Lead or Case records.
Some AppExchange applications operate under a default user account. Any changes made by the app appear in the record history as changes made by this default user, even when that user is not manually logged in. To verify, check the Login History for the default user account. If that user is logging in through a third-party app, the app may be responsible for the ownership change.
