In my Active directory 2010, I have created few users i.e. as outside contacts.
For example I have added users by their names and with their personal e-mails as "contacts in active directory". Alex (with his e-mail address i.e. alex @gmail.com ) and Ken (with his e-mail address i.e. firstname.lastname@example.org).
I have then created a distribution group by name "contract workers" for them and added these two contacts to it.
When i mail to the distribution group .... they are not getting any mails.
Please guide as how can i get this to work?
