All my security groups I created in AD (W2K3) that I mail-enabled in Exchange 2007 is showing up as "Mail Non-Universal Group". Exchange 2007 will not allow me to change or modify the group as a Mail Non-Universal Group.
As for the security groups, they are global groups which I have them that way since I only have one domain and it is not needed to replicate to all GCs. So the only two options I have here is change my security groups to universal or create a new distribution list.
Does anyone have a better way to do this or do I have to change my security groups to universal from global group?
