Your message did not reach some or all of the intended recipients.

Subject:

Sent:

The following recipient(s) could not be reached:

on

The message reached the recipient's e-mail system, but delivery was refused. Attempt to resend the message. If it still fails, contact your system administrator.

< . .com #5.2.1>



CAUSE
This problem occurs if all the following conditions are true:
 * You are running Microsoft Exchange Server 2003 or Microsoft Exchange 2000 Server in a Microsoft Windows Server 2003 domain environment.
 * Your domain structure is organized in a hierarchical domain topology, with a forest root domain and with child domains.
 * Your user account is a member of a new built-in security group that is included in Windows Server 2003. For example, your account is a member of one or more of the following built-in security groups:
 * Network Configuration Operators
 * Performance Log Users
 * Performance Monitor Users
 * Remote Desktop Users
 * Terminal Server License Servers
 * Windows Authorization Access Group

Exchange Server tries to match the security identifiers (SIDs) of the groups that you are a member of with existing groups in the Active Directory directory service. However, built-in group membership should be exempt from this process.

Exchange Server uses a function call to determine whether a SID matches a known built-in group that is stored in the Exchange store built-in groups array. However, the array does not include the new built-in groups that were introduced in Windows Server 2003.

Consider the following scenario:
 * You are a member of a new Windows Server 2003-specific built-in security group.
 * There is a hierarchical domain topology.

In this scenario, Exchange Server finds more than one match to the built-in group SID. Therefore, Exchange Server considers your alias ambiguous. Both the parent domain and the child domain contain several of the same built-in security groups.
