Hi people, I have a quick question, which I can't find in the technet/MSDN knowledge base.. i) Is it possible to create an Exchange contact list, with a list of non-Active Directory users? I.e. I have a list of corporate contacts we want to put in a public address book, but they are not part of our company. ii) I believe it's possible, but I just need to double check - can the Exchange contact information store be extended to hold more than simply contact details? i.e. can I add personalised fields to Exchange forms such as prefrable mailing list details? Thanks in advance for the help.. EggHeadCafe.com - .NET Developer Portal of Choice http://www.eggheadcafe.com
