A conflict resolution message appears on only one client computer when two users save changes to the same message in a public folder at the same time in Exchange Server 2003

Consider the following scenario. Your organization contains two public folder servers that are running Microsoft Exchange Server 2003. Two users log on to two different Microsoft Outlook client computers. The users change the same message in the public folder. Then, they save the changes to the message at the same time. In this scenario, the conflict resolution message appears on only one client computer.

This problem occurs if a backfill message is in a conflict state. When you respond to a backfill request, the conflict resolution message will not be backfilled if the conflict resolution message exceeds the size limit of a public folder. The conflict resolution message may exceed the size limit of the public folder even if the original message does not exceed the size limit of the public folder. In the scenario that is described in the "Symptoms" section, the conflict resolution message is three times the size of the original message because the conflict resolution message contains three copies of the original message.
