When moving the database, the following warning message appears:
"Warning! The maximum key length is 900 bytes. The index 'MessageSubjectIndex' has maximum length of 1500 bytes. For some combination of large values, the insert/update operation will fail."
For some combination of large values, the insert/update operation will fail after moving the database to the production SQL 2000 Sp3 Server. This is just a warning and not an error. This index gets created even if it is more than 900 bytes. This table is used only by the Message Delivery diagnostic test, and it will not affect the performance of the message delivery test.
