Some of the members in distribution group are not visible and they dont receive emails intended to that group, when you add in the EMC its says object exist.
Have anybody else faced such situation , i see that user is a member in active directory but not in the outlook and exchange console.
Any suggestions would be appreciated

Ex2k3: one old server still exist in the AD site.
