I have a few users who are using outlook 2003 and there outlook.nck file is not saving all email addresses under this file. When they start to type the person's name it pops up but when you check the properties there is no email address associated with it. The wierd this is that they have used the people before in emails and everything worked fine. I had recently moved my exchange 2000 server from one server to another server would this have anything to do with it? From my understanding of .NCK files is that it is a local file that does not get updated by exchange. Any suggestions on why this is happening?
