Color-coding for Exchange categories in Virto Calendar
Virto Calendar allows you to color-code Exchange calendar events according their categories from Exchange.
Note: This feature is available for Virto calendars for SharePoint 2010, 2013 and 2016.
For example, I need to add the category named “Blue category” to Virto calendar. Open “Advanced settings” of Exchange data source, select “Category” field and click “Add new field value and color”.
Then type the name of required category from Exchange (names must be identical).
Select a color for this category, it may not match exactly the color from Exchange.
You can add other categories with custom colors in the same way.
