Outlook.com is a widely used and free modern email service from Microsoft. It has a clean and clutter free interface and hooks right into other Microsoft services.

When you activate the integration between Outlook and Officient, registered days off of specific teams will automatically appear in an Outlook Calendar of your choosing.

Employees can subscribe to their own day off calendar, the day off calendar of their team or their team's birthday calendar. These subscriptions will appear as separate web calendars in their Outlook Calendar.

Free integration (included in Officient license)
