We have an Exchange 2013 environment on which we have created distribution groups with powershell.
However I can't figure out how we can configure the "send to" permissions for these distribution groups.
What we want is for Exchange to look at CustomAttribute3 in a user account, and if that attribute meets the set requirements the user will have permission to send mail to this distribution group.
Can anyone help me with this issue? Is there a powershell command I can use to configure this?
kind regards,
kevin
