How do I pull the list of users and their email addresses and export to a file?

Question

I started with what I have below.

$user = Get-ADGroupMember -Identity mygroup

foreach ($n in $user) {
    (Get-ADUser $n -Properties mail).mail
} 

Answer 1

Here is what worked and gave me what I wanted

$user = Get-ADGroupMember -Identity mygroup

foreach ($n in $user) {
    (Get-ADUser $n -Properties mail).mail | Add-Content c:\mygroup.txt
}
