Vanderbilt employees and students can buy Office University 2010 for PC or Office University 2011 for Mac for $99.95 for personal use through the Vanderbilt Software Store. Starting early next year, Microsoft will replace these perpetual use products with Office 365 University. Office 365 University is a subscription based service that includes SkyDrive storage, Skype minutes and streaming Office.

Employees and students who buy Office University between now and the release of Office 365 University qualify for a free subscription to Office 365 University.
