The “CampusGroups for Zoom is approved to use” email is a legitimate email. This Zoom app is relevant to those who either wish to hold virtual events or schedule virtual meetings via Zoom through What to DU (aka CampusGroups). In order to take advantage of this functionality, you must have a Denison Zoom account (see Are You Fully Set Up with Zoom for details) and be either using the Meeting Scheduler or setting up events in What to DU. 

If you have questions about Zoom, please see the Denison Zoom User Guide or contact the ITS Service Desk at servicedesk@denison.edu or 740-587-6395.
