XFOR: DirSync Cycle Removes Secondary X.400 Addresses

• Microsoft Exchange Server, versions 4.0, 5.0, 5.5

SYMPTOMS

A custom recipient's secondary X.400 addresses are removed after a successful Directory Synchronization (DirSync) cycle.

CAUSE

The user's Given Name, Surname, and/or Initials value within Microsoft Exchange Server was changed by the DirSync process. This problem will generally only be seen when mapping template information to the custom recipient's Given Name, Surname, and/or Initials field within Microsoft Exchange.

The X.400 address for Microsoft Mail for PC Networks users participating in DirSync within Microsoft Exchange is generated by the Microsoft Exchange Directory Synchronization service (DXA). When the DXA receives a modification to any of these values, it recognizes that it must generate a new X.400 address for the custom recipient because an X.400 address includes this information.

The DXA was inadvertently removing all X.400 addresses, including secondary X.400 addresses, prior to creating the new address.
