These changes are going to be later enforced in 15.20 & onwards. This update is 15.17 & is the first that has a few changes that may affect the way you deploy Office 2016. With Volume Licensing for products such as Windows 8.1, Windows Server 2012 R2, Windows Server 2012 R2 for Embedded Systems, Windows 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, Microsoft Office 2010, and Office 2013, you must use Volume Activation (VA). Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate. Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016.Soon Microsoft are to release an update to the Office 2016 Volume License installer on VLSC. Microsoft Products and Services Agreement (MPSA) customers should use the Business Center. I also ran the serializer though composer first as it is a ISO on my USB key and I made it a package so I could upload it to Jamf Pro.Register, Assign Permissions or Access Your Licenses During registration, provide the same business or organization e-mail address that was referenced in the access notification e-mail you received. To test if the serializer was still good I ran it off of the USB key I have it on and then MS word brings me to the new document window which is where I want it to be. But then when I run say word it asked me to login. I did a force run of the policy on a new macbook air and everything looks good from the terminal window, office installed first successfully and likewise the serializer. I setup the policy with both MS Office and the serializer and I even set the priorities of each software making sure that office installs first and the serializer second. I uploaded both the office and serializer software packages to Jamf. I've gone to MacAdmins and downloaded MS Office 365/2019 build 16.26 and I already have a serializer pkg that works. When I launch say word it prompts me to login instead taking me to the window where I can create a new blank document. So I'm having a problem with Office 2019 activating.
