Name changes not reflecting in users email address.
It is my understanding that if a last name is changed for a user and my Email address policy is setup correctly that email addresses will update automatically.
MY email address policy is as follows
@domain1.com (this is primary)
What am I missing in my policy, that is preventing name Exchange to populate email address and set to primary.
Lastly any change made to policy we would want old email addresses to stay in effect.
