"Get Range" button on the Delete Object Data page may return "Database Error Too many table names in the query. The maximum allowable is 256" on these conditions:
1. SQL Server is SQL 2005 (any service pack).
2. MessageStats 6.9 with at least MessageStats OWA Report Pack installed.
3. After connecting to an Exchange org, go to Database Management/Delete Data/Object Data.
4. Select the Organization filter option and click on "Get Range".
NOTE that this error only occurs when selecting the Organization option. Selecting this option dramatically increases the number of tables in the query. The error only occurs in SQL 2005 because the 256 table limit has been removed from SQL 2008
