I have really enjoyed writing this bit of code because it stretched from Trello API to Office 365 API, two of my favorite programming interfaces. This Power-Up is similar to the default Trello Calendar Power-up, the key difference being is that it connects to your Outlook Calendar. So, you can see all your Trello Tasks and your Outlook appointments/meetings, side by side in one place, you can link your appointments to Trello cards and vice-versa. With a month view and a weekly view, you can manage your calendar easily by dragging and dropping your Trello Cards on the calendar to create linked appointments for specific tasks all in one place.
