TasTrack compares the linked contact, task meaning, subject matter, deadlines, and conversation context across connected emails, messages, meetings, and calendars. For this to work reliably, you must update the contact in TasTrack with that person's details for every connected source, such as their email addresses, phone numbers, and messaging identities, so TasTrack can recognize that the activity belongs to the same contact. When new information relates to an existing responsibility, TasTrack links it to the same task and updates its due date, priority, status, follow-up information, and source history instead of creating a duplicate. If the source details are not linked to the contact, TasTrack may treat the activity as a separate contact or task.
