New-Item : Access to the path is denied - powershell

Question

I have a PowerShell script below
$ous = 'ou=office,dc=xxx,dc=com',`
'ou=shop0,dc=xxx,dc=com',`
'ou=shop1,dc=xxx,dc=com',`
'ou=shop2,dc=xxx,dc=com'
$outfile = 'c:\work\userinfo.csv'
New-Item -Force -type "file" -Path 'c:\work\userinfo.csv'
$ous | ForEach {
Get-ADUser -Filter * -SearchBase $_ |
Select-Object -Property CN,`
DisplayName,`
GivenName,`
Surname,`
SamAccountName,`
PasswordExpired,`
mail,`
Description,`
Office,`
EmployeeNumber,`
Title |
Sort-Object -Property Name |
export-csv -Append $outfile -NoTypeInformation
}
Then when I run it, I got error message "New-Item: access to the path c:\work\userinfo.csv" is denied.
What's the cause for this error?
Update:
In my case, somehow, PowerShell is case-sensitive....the output folder name is uppercase, in my script is lowercase, it works after I match them.

Answer 1

I am bypassing the reason for the error ( of which I'm not sure of the cause.). Another way to get what you want
each time I run script, I could get an fresh result without previous results
You just need to move the output code outside the loop and remove the append. Pipeline handles the Append for you.
$ous | ForEach {
Get-ADUser -Filter * -SearchBase $_ |
Select-Object -Property CN,`
DisplayName,`
GivenName,`
Surname,`
SamAccountName,`
PasswordExpired,`
mail,`
Description,`
Office,`
EmployeeNumber,`
Title
} | Sort-Object -Property Name |
export-csv -Append $outfile -NoTypeInformation
Noticed something
You are not calling all the properties you are using in your select statement. That should lead to some null columns in your output. I would update your code to something like this.
$props = "CN","DisplayName","GivenName","Surname","SamAccountName","PasswordExpired","mail","Description","Office","EmployeeNumber","Title"
$ous | ForEach-Object {
Get-ADUser -Filter * -SearchBase $_ -Properties $props | Select-Object $props
} | Sort-Object -Property Name |
export-csv $outfile -NoTypeInformation
