Hi
Currently we defined recipient policy as %1g%3s@mydomain.com with Exchange 2003. Also many users have short e-mail addresses defined manually likeabc@mydomain.com. With Exchange 2010 we defined the policy as Firstnameinitial.lastname as mail address policy. So How can we keep the existing mail addresses along with Exchange 2010 policy while migrating the users? Also is there any impact on Exchange 2010 users if we run Rebuild option with Exchnage 2003 RUS, because we modified the last name of many users to remove unwanted characters (like -, . etc), but still the it's not reflecting with email address of those users.
Thanks in Advance
