Exchange Shell

I have a spread sheet of about 100 users, and on the spread sheet I have the email addresses of the user which corresponds to their principle name. I would like to run a script in exchange shell to import these users into a variable and get their samAccountname, from the email address. I would like this exported to a csv file. Anyone has any idea on how to get this accomplished. Thanks in advance

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Disregard question, I manage to get this script to work:

$userlist = Import-Csv c:\excel\test.csv
foreach ($user in $userlist) {
$perms += @(get-mailbox -Identity $user.emailaddress)
}
$perms | select displayname, samaccountname | export-csv c:\excel\respond.csv
