Hi all, I have set up ADC as a two-way connector, and it is copying over the user information correctly from Exch 5.5 to Win2K AD, but I want to move the mailboxes and attach them to the already existing Win2K users. Any ideas how to go about this? Here is my setup: I am currently migrating users manually to a new Win2K domain. Not using ADMT or any tool, I'm doing it manually to filter out all the redundant groups and users that have accumulated. The usernames on 2K are different from the ones on NT. There is a 2-way trust between the NT and the 2K domain. I have Exch 5.5 SP4 running on one of the NT BDCs and I will be installing Exch 2k on a standalone 2K server which is part of the 2K domain. I want to move the mailboxes from 5.5 to 2000 with as little user intervention as possible. I guess this would mean putting the 2 servers within the same site. I don't mind doing that, but I want to remove my Exch 5.5 once all my users are moved over. Thanks and regards Andrea
