PowerShell export to csv. Only quote 1 set in each row

When I'm building a CSV Export it puts quotes around every set of parameters. However, I only want 1 set to have the quotes.

$UserInfo = New-Object System.Object
foreach($user in $MailBoxList)
{
$UserInfo | Add-Member -Type NoteProperty -Name LegacyExchangeDN -Value $user.LegacyExchangeDN
$UserInfo | Add-Member -Type NoteProperty -Name CloudEmailAddress -Value $CloudEmailAddress
$UserInfo | Add-Member -Type NoteProperty -Name OnPremiseEmailAddress -Value 
$user.PrimarySMTPAddress.ToString()

$UserInfo | Add-Member -Type NoteProperty -Name MailboxGUID -Value $user.ExchangeGUID

$Users += $UserInfo

}

$Users | Export-CSV -Delimiter "," -Path ".\cloud.csv" -NoTypeInformation

Select allOpen in new window

This code results in this exported CSV: "LegacyExchangeDN","CloudEmailAddress","OnPremiseEmailAddress","MailboxGUID" "/o=MyUnit/ou=This Admin Group (BRBIDOMF87SRQLT)/cn=Recipients/cn=a0dd27c5djd864108cfa61dj37dj56c6-MyLastName, M","mMyLastName@WhereverImFrom.Bob.com","mMyLastName@AnotherDomain.com","687efe5e-4690-110e-86a5-69fr4cdecf7e"

What I'd like is just the first column of data to have double quotes and the rest without: "/o=MyUnit/ou=This Admin Group (BRBIDOMF87SRQLT)/cn=Recipients/cn=a0dd27c5djd864108cfa61dj37dj56c6-MyLastName, M",mMyLastName@WhereverImFrom.Bob.com,mMyLastName@AnotherDomain.com,687efe5e-4690-110e-86a5-69fr4cdecf7e

Any thoughts?
