The Microsoft Exchange Information Store service stops unexpectedly when the Exchange Server 2007-based server replicates the Public folder

Consider the following scenario:

• You deploy a Microsoft Exchange Server 2007-based server to replicate the public folder data from another Exchange server.
• You set the event logging level for Replication DS Updates to any setting other than Lowest.

In this scenario, the Microsoft Exchange Information Store service in Exchange 2007 stops unexpectedly when the Exchange Server 2007-based server replicates the Public folder.

This problem occurs when the diagnostic logging performs string conversion.

To resolve this problem if you are running Exchange Server 2007, download and install Update Rollup 1 for Exchange Server 2007.
