Hi , After migrating to exchange 2003 from 5.5 and switching to native mode ( after native mode precisely) any universal distribution groups created on spoke sites have email addresses as group@hubsitedomainname. Also on the properties of the group, under the " exchange Advanced" tab, it shows the " administrative Group" as the hubsite domain name. Why is this happening ? I have not read this in any white papers of migration. What can be done? Thanks Raj
