The Microsoft® Exchange Server Analyzer Tool includes a performance data collection engine that is used to query performance counter objects on computers that are running Exchange 2000 Server or Exchange Server 2003. The performance data collection engine collects data from the Replication Receive Queue Size performance counter of the MSExchangeIS Public performance object to analyze performance data.

If the Exchange Server Analyzer determines that the Replication Receive Queue Size counter has exceeded the peak value of 1000 during the sample time slice, the Exchange Server Analyzer displays an error.

Public folder replication messages are received by SMTP, categorized and handed to the local SMTP queue. The messages are then submitted to the Public Folder store. When they have been submitted to the Public Folder store the messages are put in the Replication Receive Queue. The messages in the Replication Receive Queue are then processed and the changes are performed on the appropriate public folder. The Replication Receive Queue Size performance counter indicates the number of public folder replication messages waiting to be processed.

The larger the replication queue becomes, the more out of synchronization the content in the folders becomes. When replication queues grow, there is an increased load on resources as the messages in the replication queue are processed. Also, growing replication queues indicate that public folder content on the server is outdated.

No action is required in the two instances where growth in the Replication Receive Queue is expected and can be planned for:

For existing, steady state servers where public folder replicas are not being changed in bulk, this error may indicate:

To resolve this error, take the following steps:
