First off this is going to be a bit complicated, I'm starting to feel like I've painted myself into a box and now I'm trying to find a way out of the box.
A couple years ago I created a child domain for one of our remote offices. In retrospect I wish I hadn't, but that's another story. In the mean time I had to incorporate their mail domain into our Exchange server (still running 2003). I set up the mail domain, Recipient rules, etc. Mail works fine for the users I created on the parent domain for using that mail domain. Now after quite a delay (due to other issues) we are finally creating user accounts in the child domain for the users in that office. Not all the users have e-mail accounts. I set up the security on the accounts and mailboxes in the parent domain to allow the child domain users to access the mailboxes and send mail without having to enter a second set of credentials. I am running into a problem with the Offline Address Book and I have been researching for most of the day, tried multiple ways to resolve it and am still getting error message 0x8004010f when the user clicks Send/Receive and tries to download the OAB. Yes, the users are set to use Cached Exchange Mode. I've put the users into a Universal Security group and specifically granted that group rights on the OAB, waited for replication, had a user log off and back in, with no change. I've done a registry key change to specify the Default OAB DN. I can tell you that I did not run DomainPrep for Exchange in the child domain, I've been looking at that as a possible fix, but I'm not sure if that's going to do it or not. Has anyone else run into this, how did you fix it. Thanks,
