Assign Resource Account to CallQueue or AutoAttendant (Powershell)

Apparently, Microsoft magically provided the ability to create resource accounts directly Online using the New-CsOnlineApplicationInstance cmdlet BEFORE REMOVING THE HYBRID. The option to create the resource accounts was still not working from the Admin Center. I have shown this to couple of guys from Microsoft's support one of them being UC specialist from the Fast Track team and they were extremely surprised it works. We have decommissioned Skype today, 2 weeks after creating the accounts and running the services in Hybrid mode with both Direct Routing on-prem numbers and Calling Plans🙂

We have created all 150 accounts and have assigned licenses, usage locations and numbers using this:

$data = Import-Csv "C:\Users\........Production.csv" -Delimiter "`t"
$Credential = Get-Credential
Connect-AzureAD -Credential $Credential
Connect-MicrosoftTeams -TenantId "TennantID" -Credential $Credential

foreach ($item in $data) {
# Collects values to set
$UPN = $item.UPN
$displayName = $item.DisplayName
$Phone = $item.PhoneNumber
$Country = $item.Country
if ($item.Type -ne "AA") {
$AppId = "11cd3e2e-fccb-42ad-ad00-878b93575e07" # CQ
} else {
$AppId = "ce933385-9390-45d1-9512-c8d228074e07" # AA
}

# Creates the ApplicationInstance object
$Object = New-CsOnlineApplicationInstance -UserPrincipalName $UPN -ApplicationId $AppId -DisplayName $displayName

# Waits for the user to exist
while ((Get-AzureADUser -ObjectId $UPN -ErrorAction SilentlyContinue) -eq $null) { sleep 50 }

# Assigns Usage Location
Set-AzureADUser -ObjectId $UPN -UsageLocation $Country

# Assigns the license
$License = New-Object -TypeName Microsoft.Open.AzureAD.Model.AssignedLicense
$License.SkuId = (Get-AzureADSubscribedSku |where {$_.skuPartNumber -eq "PHONESYSTEM_VIRTUALUSER" }).SkuId
$Licenses = New-Object -TypeName Microsoft.Open.AzureAD.Model.AssignedLicenses
$Licenses.AddLicenses = $License
Set-AzureADUserLicense -ObjectId $UPN -AssignedLicenses $Licenses

# Waits for the license to be assigned
while (((Get-AzureADUser -ObjectId $UPN).AssignedPlans | where {($_.Service -eq "MicrosoftCommunicationsOnline") -and ($_.CapabilityStatus -eq "Enabled")}) -eq $null) {
write-host (get-date)
sleep 1
}

## Sets the phone number to the ApplicationInstance
#Set-CsOnlineApplicationInstance -Identity $Object.ObjectId -OnpremPhoneNumber $Phone

break
}
