Powershell Script to enable specific Office 365 Service

updated #powershell, #azure edit this page

Currently I’m in an Exchange Migration project to migrate all mailboxes from Exchange onPremise to Exchange Online. Yeah.. of course.. killing Exchange onPrem… again :)

I have the following situation that all users already have Office 365 Licenses assigned like E1 / E3 or E5. There are some users that don’t have all Office 365 services the license includes enabled and so there are some disabled services. The license situation is not really structured.. When I’m going to migrate the mailboxes to Exchange Online I need to enable the Exchange service for every user so they can access the mailbox.

It doesn’t sound like a big deal but the tricky part is I want to preserve the disabled services for every user. I cannot apply a default license to all users and I’m too lazy to click through all users and enable the Exchange Online switch manually..

So now I want to share with you a script that does all the magic automatically.. Maybe its also helpful for you in some situations.

Please consider:

I’m not a DEV :)

  • The Scripts works for one service at a time
  • The Script works for E1 / E3 / E5 licenses but can easily extend to include other license types
  • I write out a LOG file with the detail the script does
  • The user list can also be a CSV file
# Connect

# Load User List
$UserList = "[email protected]","[email protected]","[email protected]"
$LogFile = "C:\Users\nitz_\LOG\LicenseLog.txt"
# Troubleshoot
#$UserList = "[email protected]"
#$User = "[email protected]"

ForEach($User in $UserList){
    If (Get-MsolUser -User $User)
        $UserLicense = $Null
        $ChangeLicense = $false

        # Check what License the user has
        $LicensesAssigned = (Get-MsolUser -User $User).Licenses.AccountSkuId
        If ($LicensesAssigned -like "*ENTERPRISEPREMIUM*" -and $LicensesAssigned -notlike "*STANDARDPACK*" -and $LicensesAssigned -notlike "*ENTERPRISEPACK*"){
            Write-Host "User $User has E5"

Feel free to use this script or just to take the basic functions and improve it to fulfill your special needs.
