Of course it's possible, it's called event handling.
It can be done in any language that supports event handling and automation.
You can find tons of examples of handling different Outlook events at
www.outlookcode.com.
You can look in the Outlook VBA Object Browser for all Outlook events
associated with all the Outlook objects.
