After I install my exchange 2007 box in my network, I add email address to security groups in active directory in order to email enable all old security groups that was there before exchange came in to.
If I send email to old groups nothing happens, no email are delivery to users in the groups , for ex :
Group 1 ( old group)
Email : firstname.lastname@example.org
But if I create the security group directly from exchange server it works.
So what can I do with all olds security groups in order to email enabled them .
Data0 : AD + Global Catalog
MAIL0 : exchange server 2007 all roules
Mail: edge server
Thanks in advance
