Cleaning up the message box can massively improve the performance of BizTalk Server. The message box spool table is a classic red flag for poor performance. The correct way to cleanup the message box is by running the relevent SQL jobs as mentioned in previous posts. An alternate way is to run the bts_CleanupMsgBox stored procedure which comes as a script as part of the BizTalk Server SDK. Note this method is not supported on a production environment.
