Started out with an NT4 network running Exchange 5.5. Installed a W2K server with AD and Exchange 2K. Starting migrating users from the 5.5 server to the E2K server. Received a request to add a new user. Added the user on the W2K server and created a mailbox during that process on the E2K server. The user doesn't show up in any address list. Based on my research so far, it appears I am having a problem with the Recipient Update Service or Recipient Policies. If you look at the user attributes via ADSIedit or ldp.exe, the showInaddressbook attribute is not set. If I go into the global address list view and preview the ldap query the user shows up. I have looked at every solution I can find on the techforums and still am having no luck. I now have requests to add 3 users and can't get them to work either. Any ideas would be greatly appreciated!
