Hello All,
I am using an inherited Exchange 2010 configuration that was upgraded from 2007.
One of our Distribution Lists is based off of a security group and I wanted to change that.
I created a universal distribution list, copied the members from the original group (security) to the new group (distribution).
Then in exchange I disabled the original group. And created a new group based off of existing group and chose the new distribution group. I gave the new group the same email address as the original group had. All of that went off without a hitch.
Except when I (or anyone) sends an email to the distribution group (with copied email address), we get an undeliverable message.
I have to assume this is because of the address book in my exchange server not having been updated yet. But how do I go about forcing this update?
