Use case: Using Lucen Track, Outlook, and MS Teams to track virtual calls

Just to show you how easily you can take advantage of time tracking to help you manage one of the biggest time drains: virtual meetings (Teams Calls specifically). As we already said in our review, Lucen Track connects with Outlook to automatically retrieve your calendar events. You can also connect Lucen Track to Microsoft Teams, not only to track time directly from Teams, but also to track time for your Microsoft Teams calls, to make sure even the time spent in calls with clients is accounted for. But the two integrations can also talk to each other, to ensure total accuracy on how your time was spent.

For example, let's say you have a virtual meeting with a client from 09:00 to 9:30. One the calendar suggestion, you'll see your meeting already assigned to the correct project and client, as well as a suggested duration of 30 minutes. If the meeting runs long ( for example, 45 minutes) Lucen Track will automatically update the entry with the actual duration when you log back in.            

Conclusion

Connecting time tracking to Outlook ensures three key benefits: improved accuracy in capturing every billable minute, streamlined workflows with less manual entry, and practical productivity insights. By integrating a smart time tracking tool like Lucen Track, your team can stay organized all day long.
