Volume Licensing customers may choose either Office Standard 2013 or Office Professional Plus 2013 as compared below. (but that doesn't usually answer the questions most people have, unless you also know the purchase decisions and purchase history made by your organisation) You may have purchased a little of each, or may have purchased transition, or, add-on rights. Generally speaking, you would have signed up for either Office2013, *or* O365. Generally, it is either/or, but not both. You should check with your education-reseller, you may have some benefits for O365 in certain circumstances (it depends upon the type of your agreement, there are several agreement types), and you may have O365 benefits if you have purchased Software Assurance Licensed for Office 365 Pro Plus because we own the Office 2013 Pro Plus Volume License or do we need to purchase a separate license for Office 365 Pro Plus? We would also like to deploy Office 365 Pro Plus in certain areas. We have deployed the Office 2013 Pro Plus application on some of our computers. We are a K12 school district that purchased 1200 Office 2013 Pro Plus Volume licenses.
