# Get existing disabled licenses plus Yammer and Viva Engage core licenses, add to array
ForEach ($License in $Licenses) {
$disabledplans = @()
$License.ServiceStatus | ForEach {
If ($_.ProvisioningStatus -eq "Disabled" -or $_.ServicePlan.ServiceName -like "*YAMMER*" -or $_.ServicePlan.ServiceName -like "*VIVAENGAGE_CORE*")
{ $disabledplans += "$($_.ServicePlan.ServiceName)" }
}}
