Office 365 Calendar by Virto has a bunch of new features for you. Now, the Calendar app can display calendars from different site collections of your SharePoint tenant!
With the new options, you are able to combine all your events from any SharePoint Online calendar and from Exchange Online (Outlook) calendars as well.
The another great feature is the ability to adjust a specific calendar in the App Part for every SharePoint page! Just copy ID of required calendar to the app part properties field.
Also, you can adjust specific colors for different event types. Select a choice field, which will be used for color coded events and define custom color for each event type.
Now the color coded event will be displayed with a chosen color. The color marker on the left side of color coded events is corresponded to the data source color.
You can display the color legend by hovering the mouse point over data source name.
