So, I have located my Word 2016 templates at: /Users//Library/Group Containers/UBF8T346G9.Office/User Content/Templates/ It seems there is confusion about the directory location of saved templates. It seems some others have found problems with altering the Normal template and found no joy from MS forums. I have no issues running them concurrently. Although I did a clean install, I did not uninstall MS Office 2011 apps. I am running a brand new Macbook Pro 9,2 with Yosemite 10.10.5. I have not had the previews, and I just updated to 15.14.0 (150911). I customized the install to include only Excel, Word, and PowerPoint. I did a clean install of Microsoft Office for Mac 2016 from installers from my campus bookstore.
