Disable Yammer for all users | Office 365

I recently did an Office 365 migration where our client was using E3 licenses.  This includes a Yammer subscription, which they were not interested in using at this stage.  I was asked to disable this service for all users.

To do this, I did the following:

Get-MsolAccountSku | Format-List –property accountskuid,activeunits,consumedunits

This will show you which license pack you're currently using:

Get-MsolAccountSku | Where-Object {$_.SkuPartNumber -eq “ENTERPRISEPACK_FACULTY”} | ForEach-Object {$_.ServiceStatus}

This shows the license packs that are available for this particular O365 License:

In this case we're wanting to disable "Yammer_EDU".

Type the following:

$x = New-MsolLicenseOptions -AccountSkuId “AccountSKUID:ENTERPRISEPACK_FACULTY” -DisabledPlans “YAMMER_EDU”

Note: the bold section is the AccountSKUID which has been blurred out in this case, but can be found here:

To apply this to all users who have a current O365 license, type the following:

Get-MsolUser -all | Where-Object {$_.isLicensed -eq $True} | Set-MsolUserLicense -LicenseOptions $x

This will take ~5 minutes or so depending on the amount of users you have in your Tenant, however once this has completed, you will notice that the Yammer license is now set to 'off'.
