Consider the following scenario. You schedule the managed folder assistant to run in a Microsoft Exchange Server 2007 environment. Then, the managed folder assistant tries to journal a message that is larger than the maximum submission size. In this scenario, the Microsoft Exchange Mailbox Assistants service (MSExchangeMailboxAssistants.exe) crashes. Additionally, the following event is logged in the Application log:
Log Name: Application Source: MSExchange Assistants Event ID: 9040 Task Category: Assistants Level: Error Keywords: Classic Description: Service MSExchangeMailboxAssistants. An error has been detected due to this exception: <exception details>.
This issue occurs because the Store.exe process fails, and generates a 0x4DA (ecMaximumSubmissionExceeded) error when the MSExchangeMailboxAssistants.exeprocess tries to submit the message to the Store.exe process.
To resolve this issue, install the following update rollup:
2509911 Description of Update Rollup 4 for Exchange Server 2007 Service Pack 3
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
