#MAKE SURE YOU ARE CONNECTED TO OFFICE 365 BEFORE RUNNING THIS SCRIPT
#If you don't know how check out: http://powershell.office.com/script-samples/connect-to-Azure-AD 
#The initial script was built for Yammer removal by Vlad Catrinescu and can be found here: http://spvlad.com/1VXll7f
#Updated by Drew Madelung to support O365 Planner GA
#This script will go through all licensed users and first check if they have the planner preview license and remove it and then check for the GA O365 planner license and disable it
#This script will re-enable all other services EXCEPT planner, If you want to disable more add them comma seaparated to the $disabledplans variable. 
#For example to disable Yammer and Planner use this: $disableplans = "PROJECTWORKMANAGEMENT", "YAMMER_ENTERPRISE"
 
#Set disabled plans (only Planner to start)
$disableplans = "PROJECTWORKMANAGEMENT"
 
#Get All Licensed Users
$users = Get-MsolUser | Where-Object {$_.isLicensed -eq $true}
