We are using Exchange 2003 and 2000, we want to upgrade to 2007, so we change the modeIn the past(mix mode), when we create distribution List, it will let us choose administrative group and generator property email address.But after change the mode to native mode, it will auto fall into the first administrative group ,and generate wrong email address (becasue the recipient policy will generate address)Although user will not have any problem up to now, we affraid have other issue in future. We can use adsiedit to change it , but dont think this is good idea.Any comment on this.Thanks

Hi, I would like to explain that the by default, Exchange Native mode does not give the option to select the AG while creating a DL. Thus, I suggest that you replace the legacy site recipient policies with the new recipient policies to fix the issue.
