After deploying Microsoft Office 2016 (part of the Microsoft Office 365 subscription) end users keep being prompted to activate.
After entering in their credentials (that they use to log in to https://portal.office.com successfully), they get a message stating that the computer has been added to their account followed by another activation prompt.
When they attempt to activate over the Internet they get a somewhat ambiguous error message: “We’re sorry, something went wrong and we can’t do this for you right now. Please try again later. [ 0x80070005 ]”
To solve this problem, we’ll need to run regedit as an administrator.
In Registry Editor, under the Computer section expand HKEY_USERS, then S-1-5-20, then Software, then Microsoft, then OfficeSoftwareProtectionPlatform, then Policies, then PayloadOverride. Right click on SKUID.
In the Permissions for SKUID window highlight the Everyone group and allow it Full control. Press the Apply button to commit the changes. Then click on the Advanced button.
In the Advanced Security Settings for SKUID window, highlight the Everyone group, then check the box next to Replace all child object permissions with inheritable permissions from this object. Click the Apply button.
Answer Yes to the Windows Security prompt that pops up. Then click OK all the way through to close out all the open windows and close Registry Editor.
If you start any application from the Microsoft Office 2016 suite, it will automatically activate and you should not see the activation prompt any more.
