After an alarm is acknowledged, Veeam ONE Monitor sends a notification to users who monitor the affected object. The notification includes time and reason for acknowledging the alarm and the total number of acknowledged alarms. Note, that you will receive these notifications only if the option for sending notifications on resolved alarms is enabled. For more information, see Email Notifications.
