i added a few more exchange 2010 servers and installed the scom agent. but alerts on these new servers are only going to one user and not the DL. the other 2010 servers are sending to DL fine any idea why the new servers are not sending out alerts to dl?

Maybe someone made a custom computer group that contains your Exchange servers, but it's not a dynamic rule, meaning they add the servers manually. Maybe they are using this group for notification?Regards, Blake Email: mengotto<at>hotmail.com Blog: http://discussitnow.wordpress.com/

under subscription, I have a name called exchange 2010, conditions are raised by any instance in a specific group the groups are Microsoft Exchange 2010 All Entities Group Microsoft Exchamge 2010 All Server Computers microsoft Exchange All Server roles subscribers - 2 users and a DL group smtp channel my smtp relay send notifications w/o delay

So the first thing I would do is check the member ship of those groups. Ensure these new computers are in there. If they are, then you can do a few things quickly. First, is to disable, then enable the subscription. If that doesn't fix it, then create a new sub with the SAME criteria. Give it a different subject line. See if people start getting one or the other or both. Also, what type of server are you using to send notification, is it Exchange, Unix? I would ask your ops teams to trace any mail from the address that is used to send notification.Regards, Blake Email: mengotto<at>hotmail.com Blog: http://discussitnow.wordpress.com/

ok those machines are actually not in the exchange 2010 group. why is that?

Is the proxy enabled on the agent? JB

Honestly, proxy enabled should just be turned on for ALL servers. I have a script for SCOM R2 you can run via job on a daily basis to set proxy enabled = true for all servers. Not sure if this will work with 2012. Bradje raises a good point, ensure agent proxy is ENABLED on all your Exchange 2010 servers.Regards, Blake Email: mengotto<at>hotmail.com Blog: http://discussitnow.wordpress.com/
