I have a Windows 2003 Domain with 1 Parent Domain [i.e. abc.com] & two Child Domains [i.e. def.abc.com & ghi.abc.com], there is a trust between the domains, I can see the trusts in the Active Directory Domains & Trusts; every domain has;
-- 2 Domain Controllers
-- 1 Exchange Server
the problems I am going to mention in this post were identified lately when I tried to move user mailbox on Exchange Server in the ghi.abc.com to either the Exchange Server of the def.abc.com or the Exchange Server of the abc.com; the Exchange Move Mailbox Task ended with the following error;
>>Unable to move mailbox 'Basher Abu. AlBaghi'.
Error: The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance.
The MAPI provider failed.

the resolution to this problem that Microsoft suggests is in the following link;
http://support.microsoft.com/kb/274534I have done what is mentioned in this article; but still the problem remains; but while troubleshooting this problem I also identified the following problem;
-- While I am logged onto the Domain Controller or the Exchange Server of the def.abc.com; using the Active Directory Snap-in I cannot connect to the ghi.abc.com, but I can connect to the abc.com domain.
-- If I open the Active Directory Domains & Trusts snap-in on the server for the def.abc.com, I can see the entry for the trust between all the 3 domains, but while from the same server if I try to goto the Properties of the ghi.abc.com domain, it gives me the following error;
>>This computer was not able to set up a secure session with a domain controller in domain ghi.abc.om due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.
ADDITIONAL INFO
If this computer is a domain controller for the specified domain, it sets up the secure session to the primary domain controller emulator in the specified domain. Otherwise, this computer sets up the secure session to any domain controller in the specified domain.<<
-- Also in the Active Directory Sites & services; I can see the Domain Controllers of all the three domains, I can also see the Exchange Servers for the abc.com & ghi.abc.com domain but cannot see the Exchange Server for the def.abc.com; plus when I take the Properties of the Exchange Server entry for the domain ghi.abc.com in the Active Directory Sites & Services snap-in; I cannot see any information about the Computer or the Domain in the Properties dialogue box.
-- The final issue as I know until now is that we have Distribution Groups defined in the Active Directory for group emailing, but we have controlled access to the users as to who should be able to send to these groups, now if I want to modify the members of a particular group on the Exchange Server for def.abc.com, it gives me the following error message;
>>Microsoft Active Directory - Exchange Extension
A referral was returned from the server
Facility : LDAP Provider
