Office 365 Unlicensed Product Error
This has been an on going issue for most people using Office 365 licensed Office products since the beginning.
After a period of time (Sometimes a password change sets it off) Your user might get the error (Unlicensed Product) in the banner when opening an Office product like Word or Outlook.
There are two different fixes, one for Office 2010 & another for Office 2013.
You need to open a command prompt (I would elevate) and run the following.
32bit: C:\Program Files\Common Files\Microsoft Shared\OFFICE14\OSAUI.exe /F
64bit: C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE14\OSAUI.exe /F”
You need to go to one of these locations first and then run the script below
32bit: C:\Program Files\Microsoft Office\Office 15\
64bit: C:\Program Files (x86)\Microsoft Office\Office15\
Now run: cscript OSPP.vbs /act
This should bring up am activation window which should show “Successful” after completing.
Hopefully this will help you solve your Office 365 Office Licensing issue.
