While setting up a new user I got this error when opening Outlook 2016:
“We’ve run into a problem with your Office 365 subscription, and we need your help to fix it.”
The problem: Bad product key.
The fix:
Open a command prompt as administrator and run:
“c:\program files (86)\Microsoft Office\Office16\cscript ospp.vbs” /dstatus
You’ll get a bunch of output – you’re looking for the last 5 characters of the installed product key. Find that key and enter this line:
“c:\program files (86)\Microsoft Office\Office16\cscript ospp.vbs” /unpkey:last five of key here
That’s it!
