We recently came across an issue for our customer where their Office ProPlus would not activate even though the user had a license.
The first step was to find out the last 5 digits of the license key that Office was currently using by running the following command:
C:\Program Files <x86>\Microsoft Office\Office16>cscript ospp.vbs /dstatus
From the output of this command, you can take the last 5 characters and unregister the product using the following command:
C:\Program Files <x86>\Microsoft Office\Office16>cscript ospp.vbs /unpkey:”Product Key”
After running this command you should now be able to reopen Office applications and activate successfully!
