Hi @Iniobong Nkanga ,
The article said,
"If you bought your subscription through Volume Licensing or a Cloud Solution Provider (CSP), you can't buy Office 365 Extra File Storage directly from Microsoft. Contact your representative or partner for help",
But you said,
”This was purchased via volume licensing, but the issue isn’t with the “Partner”. “,
"The licensing was purchased and invoiced correctly."
In other words, you are sure that you have made the correct purchase through the partner, right? Can you provide some screenshots about this?
Make sure that the license is correctly assigned and enabled for your users. Sometimes, signing out of Office and signing back in can refresh the license assignment.
