In a mixed Microsoft Exchange environment, public folders can be replicated from Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 to Microsoft Exchange Server 2007 Service Pack 1 (SP1). However, in some cases, the public folder replication messages stay in the MapiDelivery queue. These messages are retried periodically on the Exchange Server 2007 SP1 server that has the Hub Transport role installed. Therefore, the Exchange database grows quickly and exhausts the disk space. Additionally, the following warning or error messages are logged repeatedly when this problem occurs.
Event Type: Warning Event Source: MSExchangeIS Public Store Event Category: Transport Delivering Event ID: 2091 Description: A message deliver to public folder store "<Storage Group>\<Store>" with message class IPM.NOTE is being dropped
Event Type: Error Event Source: MSExchangeIS Public Store Event Category: Replication Errors Event ID: 3093 Description: Error -2147221233 reading property <xxxxxxxx> on object type tbtMsgFolder from database "<Storage Group>\<Store>".
This issue occurs when Exchange Server 2007 SP1 cannot convert certain replication messages to MAPI items because the messages are missing some TNEF data. In this case, Exchange 2007 SP1 RU7 incorrectly generates an error and the error messages that are mentioned in the "Symptoms" section are submitted repeatedly.
To resolve this problem, install Update Rollup 9 for Exchange 2007 Service Pack 1. For more information about Update Rollup 9 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
