Virto Calendar enables users to view all of their events from different data sources (SharePoint List, Microsoft Exchange Calendar or SQL Tables) in one single calendar, sparing the necessity to switch between multiple views. Another value offered is the ability to bind from different data sources - from SharePoint lists, Microsoft Exchange Calendars and SQL tables, to create a new calendar event. This exceeds most other calendars that can only use one data source, and be displayed in only one view. Virto Calendar surpasses the existing SharePoint calendar view's functionality by allowing users to specify the list or view, and also color code the displayed items by category of events (such as internal or external, view day, week, month, year, and Gantt view).
