I migrate my WinNt4.0 PDC to Win2000 server as domain controller.
After I migrate users and groups successfully. It came to my attention that all users can not retrieve their E-mails, then I noticed that my WinNT4.0 Exchange 5.5 sever is not working with my new active directory.
Is there anything that I have to do to make my Exchange 5.5 work with my new Active Directory?

Yes, you have to use the Active Directory Connector to replicate between Exchange 5.5 and active directory. Exchange uses Active Directory Connector (ADC) to populate Active Directory with routing information from earlier Exchange organizations, allowing different versions of Exchange to coexist on the same messaging network.

One more thing, you will also have to run forest prep that will modify active directory specificaly for exchange! Im sending you a good document on this. You can also go to http://www.microsoft.com/exchange for good whitepapers on the process.

You can use the ADC to replicate your directory information from the Ex5.5 directory to AD, but it is not required for Ex5.5 to work on Win2k. To the Ex5.5 server the user account should behave just as they did when the domain was an NT4 domain.
Can you verify that the user accounts are still attached to the appropriate mailbox. Also, can you use the Exchange Service Account and access anyone else's mailbox.
As for NTOz's answer /forestprep is an Exchange 2000 setup switch, and has nothing to do with Ex5.5 Operating in a AD environment, but it does have everything to do with getting Exchange2000 running in your domain or migrating from Ex5.5 to Ex2K.
