DirectReports Array inside of another Array

Question

So i am trying to make this directReports Array to parse into the CSV, but i cant get the syntax right. Can anyone help here?
function Release-Ref ($info) {
foreach ( $p in $args ) {
([System.Runtime.InteropServices.Marshal]::ReleaseComObject(
[System.__ComObject]$p) -gt 0)
[System.GC]::Collect()
[System.GC]::WaitForPendingFinalizers()
$olFolderContacts = 10
$objOutlook = new-object -comobject outlook.application
$n = $objOutlook.GetNamespace("MAPI")
$colContacts = $n.GetDefaultFolder($olFolderContacts).Items
$xl = new-object -comobject excel.application
$xl.Visible = $True
$wb = $xl.Workbooks.Add()
@{ directReportsExp = 'directReports'; Expression = { $_.directReports -join ';'; }; }
$ws = $wb.Worksheets.Item(1)
$ws.Cells.Item(1, 1).Value() = "First Name"
$ws.Cells.Item(1, 2).Value() = "Last Name"
$ws.Cells.Item(1, 3).Value() = "Manager"
$ws.Cells.Item(1, 4).Value() = "Directly Reports to"
$ws.Cells.Item(1, 5).Value() = "Job Title"
$ws.Cells.Item(1, 6).Value() = "E-mail Address"
$i = 2
foreach ($c In $colContacts) {
if ( $c.Email1DisplayName -ne $Null ) {
$email = $c.Email1DisplayName.Split( '(' )
$ws.Cells.Item($i, 1).Value() = $c.FirstName
$ws.Cells.Item($i, 2).Value() = $c.LastName
$ws.Cells.Item($i, 3).Value() = $c.ManagerName
$ws.Cells.Item($i, 4).Value() = $c.directReportsExp
$ws.Cells.Item($i, 5).Value() = $c.JobTitle
$email = $email[1].TrimEnd( ')' )
$ws.Cells.Item($i, 6).Value() = $email
$i++
$r = $objWorksheet.UsedRange
$r.EntireColumn.Autofit
$a = Release-Ref $r $ws $wb $xl

Have you tried Export-Csv? I can't comment on the syntax for the excel com stuff as it's something I never use, but Export-Csv is built in and works well to output Powershell objects to a csv file.
You're doing quite a bit in the function - you might want to do less. You should just output the objects you need and then you can process those in the pipeline. For instance:
[PsCustomObject]@{
'First Name' = $Contact.FirstName
'Last Name' = $Contact.LastName
'Manager Name' = $Contact.ManagerName
'Directly Reports To' = $Contact.directReportsExp
'Job Title' = $Contact.JobTitle
'E-mail Address' = $Email
This will output an object that can be piped to export-csv:
Release-Ref | Export-Csv -Path c:\directreports.csv -NoTypeInformation
Also, there are definitely some things you should do differently in the function itself. Why not fully parameterize the function instead of using $args? This tutorial may help:
