Event Id3091
SourceMSExchangeIS Public Store
DescriptionError <error code> occurred while processing an incoming replication message. Folder: <folder name>
Event InformationExplanation :
This event is logged if the diagnostic logging for public folder replication has been turned up, and if there are problems processing incoming replication messages. The causes for a failure to process can be varied. Check for related events in the application log for more information. It is possible that the public folder store on the Exchange Server is corrupt, but this is not definite. Also, if the public folder store to which replication has been configured does not have the hierarchy replicated to it (you will need to investigate the reason for this), then this event could occur.
User Action :
Ensure that the latest service pack for Exchange Server has been applied. Check for related events in the application log. Ensure that the hierarchy has replicated to the target public folder store to which replication has been configured.
