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

Question

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
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?

You can "roll your own" csv file:
$Outfile = ".\cloud.csv"
'LegacyExchangeDN,CloudEmailAddress,OnPremiseEmailAddress' | Set-Content $Outfile
foreach($user in $MailBoxList)
{
$Data = #(
$user.LegacyExchangeDN,
$CloudEmailAddress,
$user.PrimarySMTPAddress.ToString()
)
'"{0}",{1},{2}' -f $Data | Add-Content $Outfile
}

Here's one solution. What it does is convert the objects to csv-strings and then modify them before saving the csv to a file.
foreach($user in $MailBoxList)
{
$UserInfo = New-Object System.Object
$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
}
#Convert to csv-formatted-strings
$csv = $Users | ConvertTo-Csv -NoTypeInformation -Delimiter ","
#Get header
$out = #($csv[0])
#Remove quotes for all but first column
$out += $csv[1..($csv.Length-1)] | % {
[regex]::Match($_,'(^"[^"]*",)(.*)') | % { "{0}{1}" -f $_.Groups[1], $_.Groups[2].Value.Replace('"',"") }
}
$out | Set-Content -Path ".\cloud.csv"
Another apporach without regex:
#Remove quotes for all but first column
$out += $csv[1..($csv.Length-1)] | % {
$values = $_ -split '","'
$values[0] + '"' + $values[1..($values.Length-1)] -join ','
}
