- If you select the setting based on unusual activity, Microsoft establishes a baseline value that defines the normal frequency for the selected activity. It takes up to seven days to establish this baseline, during which alerts aren't generated. After the baseline is established, an alert is triggered when the frequency of the activity tracked by the alert policy greatly exceeds the baseline value. For auditing-related activities (such as file and folder activities), you can establish a baseline based on a single user or based on all users in your organization; for malware-related activities, you can establish a baseline based on a single malware family, a single recipient, or all messages in your organization.
