run powershell command using csv as input

Question

I have a csv that looks like

Name, email, address
Name, email, address
Name, email, address

I am wanting to run

Answer 1

$csv = Import-Csv c:\path\to\your.csv
foreach ($line in $csv) {
    New-Mailbox -Name $line.Name -WindowsLiveID $line.Email -ImportLiveId
}

First line of csv has to be something like Name,Email,Address

If you cannot have the header in the CSV, you can also have:

$csv = Import-Csv c:\path\to\your.csv -Header @("Name","Email","Address")

-Header doesn't modify the csv file in any way.
