Exchange ActiveSync powershell Report

Question

Good Day All,
I am trying to run a a script, which pulls a report of all of our activesync devices and exports from powershell to .csv. The report runs fine but I have to manually format the result because the csv does not split into individual columns. Any assistance
in getting the headers and linked info to split into individual columns would be highly appreciated.
Below is the script:
$Mailboxes = Get-Mailbox -ResultSize "unlimited"
$Date = Get-Date
$CSVPath = "c:\reports\ActiveSyncReport.csv"
$CSVHeader = "DisplayName,Department,PrimarySMTPAddress,DeviceType,DeviceModel,DeviceOS,FirstSyncTime,LastSuccessSync"
$CSVHeader | Out-File -FilePath $CSVPath -Encoding ASCII
Foreach ($Mailbox in $Mailboxes)
$ActiveSyncInfo = $null
$ActiveSyncInfo = Get-ActiveSyncDeviceStatistics -Mailbox $Mailbox | Where-Object {$_.LastSuccessSync -ge $Date.AddDays(-30)}
If ($ActiveSyncInfo -ne $null)
$ADInfo = Get-ADUser -Identity $Mailbox -Properties "Department"
$DisplayName = $Mailbox.DisplayName
$Department = $ADinfo.Department
$PrimarySMTP = $Mailbox.PrimarySmtpAddress
$DeviceType = $ActiveSyncInfo.DeviceType
$DeviceModel = $ActiveSyncInfo.DeviceModel
$DeviceOS = $ActiveSyncInfo.DeviceOS
$FirstSync = $ActiveSyncInfo.FirstSyncTime
$LastSuccess = $ActiveSyncInfo.LastSuccessSync
[String]$CSVAdd = $DisplayName + "," + $Department + "," + $PrimarySMTP + "," + $DeviceType + "," + $DeviceModel + "," + $DeviceOS + "," + $FirstSync + "," + $LastSuccess
$CSVAdd | Out-File -FilePath $CSVPath -Encoding ASCII -Append

Nevermind, I have managed to get it fixed, was not thinking properly. Incase it is useful to anyone else please see the below:
$Mailboxes = Get-Mailbox -ResultSize "unlimited"
$Date = Get-Date
$CSVPath = "c:\reports\ActiveSyncReport.csv"
$CSVHeader = "DisplayName;Department;PrimarySMTPAddress;DeviceType;DeviceModel;DeviceOS;FirstSyncTime;LastSuccessSync"
$CSVHeader | Out-File -FilePath $CSVPath -Encoding ASCII
Foreach ($Mailbox in $Mailboxes)
$ActiveSyncInfo = $null
$ActiveSyncInfo = Get-ActiveSyncDeviceStatistics -Mailbox $Mailbox | Where-Object {$_.LastSuccessSync -ge $Date.AddDays(-30)}
If ($ActiveSyncInfo -ne $null)
$ADInfo = Get-ADUser -Identity $Mailbox -Properties "Department"
$DisplayName = $Mailbox.DisplayName
$Department = $ADinfo.Department
$PrimarySMTP = $Mailbox.PrimarySmtpAddress
$DeviceType = $ActiveSyncInfo.DeviceType
$DeviceModel = $ActiveSyncInfo.DeviceModel
$DeviceOS = $ActiveSyncInfo.DeviceOS
$FirstSync = $ActiveSyncInfo.FirstSyncTime
$LastSuccess = $ActiveSyncInfo.LastSuccessSync
[String]$CSVAdd = $DisplayName + ";" + $Department + ";" + $PrimarySMTP + ";" + $DeviceType + ";" + $DeviceModel +
";" + $DeviceOS + ";" + $FirstSync + ";" + $LastSuccess
$CSVAdd | Out-File -FilePath $CSVPath -Encoding ASCII -Append
