Problem: Customer has a few email domain names and are slowly migrating to Office 365. The customer wants to auto assign license for certain domains using PowerShell.

Step 1:

Set the Office 365 tenant password in a TXT file.

The PowerShell Script:

#Modify below YOURPASSWORD to your Office 365 password
$password = “YOURPASSWORD”
$password | ConvertFrom-SecureString | Set-Content c:\o365\password.txt

Step 2:

Search based on the valid domains and add license for users that have not been licensed.

The powershell script:

#Valid Domains.
#Modify below domainA.com and domainB.com to your own domain that you want to auto assign license.
$validDomains =”*@domainA.com”,”*@domainB.com”

$MsolAdmUser = “admin@USERTENANTNAME.onmicrosoft.com”
$pwd = Get-Content c:\o365\credmsol.txt | ConvertTo-SecureString
$cred = New-Object System.Management.Automation.PSCredential $MsolAdmUser, $pwd

# CONNECT TO 365
Import-Module MSOnline
Connect-MsolService -Credential $cred

$temp = (get-msoluser -all) | select userprincipalname

foreach ($a in $validDomains){

foreach ($b in $temp){

$validUser = ($b) | where {$b.userprincipalname -like $a}

If ($validUser –eq $null){

} else{

set-msoluser -userprincipalname $validUser.userprincipalname -usagelocation “MY”

set-msoluserlicense -userprincipalname $validUser.userprincipalname -addlicenses “userTenantName:STANDARDWOFFPACK“

$validUser = $null

}

}

}

To get the “userTenantName:STANDARDWOFFPACK“, you will need to run get-msolaccountsku.

The above is a script that I quickly developed. Apologies if it isn’t neat as of now 🙂
