I have my SBSusers folder in AD and created another OU for my contacts for people with outside email addresses in AD. Initially I built my distribution groups in AD and it allowed me to use both my contacts and my SBSusers to build my lists, and they all show up accurately. But when I go in to SBS and go to the groups on the management console, it shows my distribution groups....but all of the contacts are missing from the lists here, only the employees show up. The distribution lists show up in active directy correctly , but not when viewing the lists in the SBSconsole. And when I try to edit the lists from the sbs console , it only shows my sbs users for choices, it doesn't give me the choice of adding from my contacts. So in Outlook we are seeing the distribution lists, minus the outside contacts that should be members of the list, and only seeing and sending to the employees addresses. Any advice is greatly appreciated.
