Running 2008 r2 with Exchange 2010 sp2
Our board of directors is comprised of both internal and external users.
We created a distribution list to include all members which works no problem.
Now management is asking that when we send our board materials, the external users would only get a notification email that lets them know a new email is waiting for them on our internal server. So we created internal user accounts with mailboxes for them. So we need to figure out a way to get the "email notifier" set up. Even something 3rd party if necessary.
Basically the notifier would contain a link to our webmail and the board member will follow that link and login with their user account info we have created.
