I do volunteer work for my church where they have an older Exchange 5.5 on a Compaq. They also have a newer, Dell 1400 server with Active Directory and Exchange 2000 on it. 5.5 server: Windows 2k Adv. Server SP2, Exchange 5.5 SP4 Ex2000 Server: Windows 2k adv. server SP2, Exchange 2000 SP2. ADC installed, etc. The 5.5 server will not fully boot. It just sits there saying "Preparing Network Connections..." Looks like a hard disk error or controller error. The server will boot in Safe Mode with Networking, so I can get the db files off of it and perhaps try ExMerge?? Even before this crash, I was going to migrate the mailboxes from 5.5 to 2000, but I can't get any accounts to logon to the new Exchange 2000 server other than the Administrator account. In other words, if I create a new User in Active Directory and create a new Exchange 2000 mailbox for them, they can't attach to it from Outlook. The Administator can attach to his mailbox, but no one else. I thought it migh be a permissions issue or something, but each person has "Full Mailbox Access" under the Exchange Advanced tab. What could I be missing? I need some ideas: 1. How to restore the mail from the DB files off the old Exchange 5.5 server... Exmerge to PST... then import into Outlook? 2. How can I fix Exchange 2000 so users can login to their new mailboxes? (re-install Exchange 2000??) Thanks!
