Powershell foreach results to array - powershell

Question

I'm trying to run the below code and get the results to an HTML email. If I just run it as is, all of the output is on one line, which is a mess. I thought I could save the foreach right to an array, but that's not working. . . Just getting a blank array. If I run it without, I get output to the screen, so I know I'm getting results.
Connect-MsolService -Credential $Credential
$customers = Get-MsolPartnerContract -All
$body = #(foreach ($customer in $customers) {
if ($customer.defaultdomainname -notlike "*Domain1*" -and $customer.defaultdomainname -notlike "*DomainABC*") {
Get-MsolUser -All -EnabledFilter EnabledOnly -TenantId $($customer.TenantId) | ? {$_.StrongAuthenticationRequirements.State -eq $null -and $_.isLicensed -eq "TRUE"} | select UserPrincipalName
}
})

I don't have an instance to play/validate with, but try it this way (use whatever code or other formatting you choose of course):
Connect-MsolService -Credential $Credential
[System.Collections.ArrayList]$body = #()
(Get-MsolPartnerContract -All) |
ForEach-Object {
if ($PSItem.defaultdomainname -notlike '*Domain1*' -and
$PSItem.defaultdomainname -notlike '*DomainABC*'
)
{
$body.Add(
(
Get-MsolUser -All -EnabledFilter EnabledOnly -TenantId $($PSItem.TenantId) |
Where-Object {
$PSItem.StrongAuthenticationRequirements.State -eq $null -and
$PSItem.isLicensed -eq 'TRUE'
}
).UserPrincipalName
)
}
}
