Get-Child Item access is denied RRS feed

  • Question

  • Hello,

    Trying to find all .PST on a local machine and my script is working but shows access is denied which i believe its trying to search a blocked folder in C:\Windows which i dont want to search for.

    I've tried !S on attributes to stop it searching for system files but still no joy any ideas .

    if ($true) {Get-ChildItem -path c:\ -Recurse -Include *.PST -ErrorAction SilentlyContinue -Exclude $dontwant -Attributes !S
    Write-host "Found PST"}

    Here is the output

    Directory: C:\temp

  • Why check the entire C drive? doubt any normal user would move a PST outside of their own home folder.

    You could use a try catch statement to catch the error and either disregard them or output the error in a more custom way.

  • Hi NathanPEdwards,

    Scanning the whole system drive to find an .PST-file makes no sense when you have propely configure your environment. In the normal way a .PST-file will be stored in the userfolder C:\Users\%username%\AppData\Local\Microsoft\Outlook(IMAP or Exchange Cache) or in the C:\Users\%username%\Documents\Outlook-files(POP3).

    See this example for scanning a userfolder:

    $ErrorActionPreference = "silentlycontinue"
    $Extension = "*pst"
    $TargetFolder = "C:\users\peterpan"
    Get-Childitem $TargetFolder -Include $Extension -Recurse

    If you still want to scan the whole system drive, exclude the system folders:

    $ErrorActionPreference = "silentlycontinue"
    $Extension = "*pst"
    $TargetFolder = "C:\"
    $Exclude = @("PerfLogs", "Backup", "boot", "MSOCache", "programdata", "Recovery", "Windows", "Program Files", "Program Files \(x86\)", "System Volume Information" , '\$Recycle\.Bin', "Config\.Msi")
    try {
        $error.Clear()
        Get-Childitem $TargetFolder -Include $Extension -Exclude $Exclude -Recurse
    }
    Catch {
        $ErrorMessage = $_.Exception.Message
        Write-Host "Error: $ErrorMessage" -f Red
        break
    }

    I think that you have enough information to go further. If you have any questions do not hesitate to ask them.


    Cheers,

    Martien van Dijk

  • Many thanks you have pointed me exactly where i needed to go ! 

    I know users shouldn't have saved PST outside their profile but users being users we have to find them as we had a situation a while ago where a machine popped and it had an old archive on the local drive.
