Apple's Volume Purchase Program (VPP) allows institutions to purchase apps in volume and distribute them to employees or staff via the Mac App Store.
While MSG Viewer for Outlook (alt: web link) is not eligible for VPP due to its use of in-app purchase for licensing, we offer MSG Viewer for Outlook Pro (alt: web link) which is the identical version of the software bundled with the license.
Alternatively, we offer Volume discounts via website purchase.
