I need to create a distribution list in exchange 2007. The customer has all his clients listed in an excel sheet and he asked me to make them import it for his staff to send mails like they would to their global address list. How do I create this? The catch is that none of the users, or users with external email adresses should be included when the mail distribution is done.
They should also be able to add, edit or delete recipients.
Thank you in advance.
