Hello Everyone

I'm looking for a solution so that we can e-mail all our parents. We are running Sims Learning Gateway which means we have the AD Provisioning Service running. When a new Contact is added to a student we provision that contact so that they have an AD User Account to login. This also means that the User has an e-mail field with their home e-mail address in it. Exchange in it's own unique way wont accept any Users in a distribution group which are not mail enabled, of course if you mail enable them that means that they have a mail box on our system which they would have to check (a non-starter).
THe only way I can see or find documented to be able to e-mail out to these parents would be to create a Contact for each parent as well as their user account and add these contacts to the relevent groups.

How do you do it?
