The InTune Company Portal application is required to use Box. If you do not already have it installed on your device, you can view instructions on how to download and install it on Rutgers Enabling Mobile Device Management for Android page.
If you previously installed the standard version of Box (without the briefcase in the orange circle) you should remove it from your device unless you have another Box account that you plan on accessing using that application. The Box application from the regular Google Play store will not work with Rutgers Box.
