As part of your subscription, we record the triggers you apply to your calendar so that we can track updates against CalendarRules rules updates.  If a rule is updated that relates to a trigger or event you have used, we set a flag on your account indicating such. DocketCalendar for Outlook will check this flag every night, and if true, provide you with a notification so you can easily recalculate the event, delete the event, or in some cases add a new event under the trigger in question. Most rule updates are effective moving forward, and only apply retroactively where “just and practicable”, which is rarely the case. Attorneys need to make this decision on a case by case basis.
