I have a POWERPOINT 2016 Presentation linked with several hundred links to EXCEL 2016, running on Windows 10. I know how to save them so they open as a SLIDESHOWs, but the links don't update. Is there a way that I can have someone open and start POWERPOINT as a SLIDESHOW, where the links WILL BE UPDATED? (One has macros thus .ppsm and one doesn't, therefore .ppsx.) Thanks!
