I wrote a blog post year ago on how to get count of MS Office Editions with versions installed across my environment using SCCM Configmgr. This report consists of 2 reports .1st report is ,to get count of Microsoft Editions for ex: how many are office 2003, 2007 ,2010 and 2013 ,2016 and 2nd report is actually drilled report linked to 1st report to give list of all MS Office editions (what are the editions of office 2003 ,2007,2010 and 2013, 2016) with its client count .
Many of my blog viewers have requested via comments secttion and some of them are via social networking sites ,that they want drill down the 2nd report to see the list of clients with each office edition and version.
Having drilled report to see the list of clients will certainly help to investigate and upgrade them to latest version of Microsoft office. Read complete post from http://eskonr.com/2016/09/sccm-configmgr-report-for-count-of-ms-office-versions-updated-with-list-of-clients/
