Hi, im fairly new to programing and have been trying for hours to try and even find documentation to help me complete a task at work. So far i have had no success so I would really appropriate any help you could give What i need to do is set up a global address list that thatwill automatically update with anyone that one of the users sends an email to. For example if i send an email to bob then Fred who also works for the same company as me can also see who bob is. I have looked around a lot online and so far have managed to create a new GAL, i cannot however get it to update with new contacts. I am using windows exchange server 2007 SP1 Thanks in advance for any help, Tom

First of all, You never want to manualy Edit the GAL. Many internal processes reference the GAL and will break if you modify it. As for the 2nd task, I hate to use the word "impossible" but i think it might be fitting here... A more realistic approach is for something to read your sent items folder and parse out the "TO:" addresses. you could then use that list and make AD contacts with the Exchange 2007 SDK and then put them in a seperate address list - but not the Global Address list. I'm pretty confident there is no way to do this automaticly. You'd have to create some custom code to run the parse, then again to use ldap to update the Address List. Create an OU called foo then make a DDG based on the OU you put these contacts into http://technet.microsoft.com/en-us/library/aa996561(EXCHG.80).aspx then make something custom to parse sent items, or message tracking logs, or smtp protocol logs then create contacts, in the earlier defined foo OU http://msdn.microsoft.com/en-us/library/aa493948(EXCHG.80).aspx Saving Contacts to Active Directory
