Vista - Set new primary SMTP-addresses in Exchange 2007

Here is a script that sets new Primary SMTP-addresses for existing
users from a csv-file

It is a very simple script, and easy modifiable.

# FILE: setsmtp.ps1

write-host 'File to be imported: ' $file -foregroundcolor "yellow"

write-host $file

$Csv = Import-Csv $file
