Your contacts, emails, and other Outlook event features can all be integrated with Microsoft Outlook Calendar, the scheduling tool that is offered to Outlook users. You may arrange group events, individual appointments, and meetings with Outlook Calendar.

With a user-friendly UI, it functions as a personal task manager. Anybody on your team can receive the calendar and subscribe to one another's calendars to receive real-time updates. This allows anyone to access and manage their own schedules.

iOS and Android devices support using Outlook Calendar. Although Microsoft is making efforts to enhance it, the Outlook Mac version is not very useful. If you are a fan of Windows and use desktop applications more often, this calendar tool can help you be more productive. The free version of Outlook can fulfill your basic needs, like providing drag-and-drop options to create a meeting or a task and sending a meeting request. If you want Microsoft Office with more features, you can upgrade to the Pro edition.
