Assign Yammer license to all licensed users Office 365

[Test SharePoint]

Hello

I need help in adding Yammer to all licensed users in Office 365.

We already have bunch of licenses for all the users. For example, each user has Enterprise E3, Enterprise mobility + Security E3, ATP.

However the sub license: yammer is unchecked in E3 Plan.

I tried doing through powershell however all the scripts were based on location and disabling licenseoptions.

Is there a script for all licensed users (or by usage location: US) to add yammer add on in E3?

I tried the script from: https://gallery.technet.microsoft.com/Bulk-Assign-License-with-5477e8e2#content

however I get the error as :Set-MsolUserLicense : Unable to assign this license because it is invalid. Use the Get-MsolAccountSku cmdlet to retrieve a list of valid licenses.

I have used the Get-MsolAccountSku command and got the same results. Not sure if I am missing something


Thank you.
