I think we all have had a moment where we wanted to create a new user account but the licenses for Office 365 had run out. Our Sysadmins asked me to write a script which would send an e-mail if the licenses almost would run out.

I would run the script from a management server which is able to send e-mail via an Exchange server or similar relay server. Furthermore the user that runs the script doesn’t need admin permissions in Office 365. You can just create a regular user account to run the script. To check whether your user account has the right permissions do the following.

Log on to Microsoft 365 Powershell via the following command:

Connect-MsolService

Then run the following command:

Get-MsolAccountSku

You will see something like:

You will probably see more output because you have more licenses activated. Everything after “:”, in the example “SPE_E5”, is the official microsoft licensename. For Office 365 E3 it’s tenantname:ENTERPRISEPACK.

In the following example the licenses for Office 365 E3 and EMS E3 are checked and if there are less then 3 available an e-mail will be send. Check it out:

$User = "Username" 
$PWord = "EncryptedPassword" #How To create EncryptedPassword "EnterPassword" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString
$secPword = ConvertTo-SecureString $Pword 
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $SecPWord

Connect-MsolService -Credential $Credential

$Office365E3Licenses = Get-MsolAccountSku | Where-Object {$_.AccountSkuId -eq "tenantname:ENTERPRISEPACK"}
$Office365E3LicensesAvailable = $Office365E3Licenses.ActiveUnits - $Office365E3Licenses.ConsumedUnits

$EMSE3Licenses = Get-MsolAccountSku | Where-Object {$_.AccountSkuId -eq "tenantname:EMS"}
$EMSE3LicensesAvailable = $EMSE3Licenses.ActiveUnits - $EMSE3Licenses.ConsumedUnits

if ($Office365E3LicensesAvailable -lt 3) {
   Send-MailMessage -SmtpServer "SMTPServer" -To "E-mailaddress" -From "E-mailaddress" -Subject "Office 365 E3 Licenses almost run out!" -Body "There are $Office365E3LicensesAvailable Office 365 E3 licenses available" -BodyAsHtml 
}

if ($EMSE3LicensesAvailable -lt 3) {
    Send-MailMessage -SmtpServer "SMTPServer" -To "E-mailaddress" -From "E-mailaddress" -Subject "EMS E3 Licenses almost run out!" -Body "There are $EMSE3LicensesAvailable EMS E3 licenses available" -BodyAsHtml 
}

If you have any questions don’t hesitate to ask.
