Hello, Exchange 2003 here. I have created many contacts in Active Directory from an excel sheet that contained a list of participant from a previous meeting. These participants are external contacts (so they have @gmail, @hotmail,...addresses). I have created a distribution list, and added as members all these new contacts. When i send an email to the DL, i receive an NDR for all contacts: CN=wim.tang@coco.com,OU=AIR,OU=Acme Events,OU=Distribution Lists,OU=Users,OU=Amsterdam,DC=corp,DC=acme,DC=local on 5/2/2012 11:56 AM The e-mail address could not be found. Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address. Check the address and try again. <corpexch01.corp.acme.local #5.1.0> What i am doing wrong?
