Found a number of these over a 2 minute span - Error 0x8004010f occurred while cleaning up background folder It gives the database name, but not the folder or mailbox name, using a number and letter series to describe the folder. Is there any way to determine where exactly this error is coming from? Ted

Hello, In a nutshell event 1097, from MSExchangeIS Mailbox Store, is logged during the online maintenance pass when the online maintenance process cannot delete certain items according to retention policies for example. Exchange store maintenance is the term applied to a series of operations performed by the Microsoft Exchange Information Store service to ensure logical consistency in the databases.The operations ensure items no longer needed by the system are removed from the database. Overall, there are 10 tasks performed by the Microsoft Exchange Information Store service during this period.If the maintenance window ends before one of the 10 tasks is completed, the last task running is recorded. The last task will be allowed to run until completion, which could exceed the maintenance window. During the next maintenance window, the Microsoft Exchange Information Store service determines the last task in progress and restarts the process, essentially picking up where it left off on the next task. If at least one of the maintenance tasks was able to complete within the maintenance schedule, the Microsoft Exchange Information Store service requests that ESE begin an online defragmentation cycle. This process will run for at least 15 minutes at the end of the maintenance window. It is important to note that the online defragmentation process will suspend itself if a backup starts for any database in the storage group.If a pass of the online defragmentation was interrupted due to window expired or backup initiated, the 1097 event is logged. You can safely ignore it. You might also try to increase the online maintenance interval and make sure that backup job is not initiating within maintenance window. That should get rid of it.Check out also : http://technet.microsoft.com/en-us/library/aa996226(EXCHG.65).aspx and http://support.microsoft.com/kb/159306 for more info on this. Hope it helps, Mihai
