How Messaging Server Satisfies Business Needs

Messaging Server promotes superior reliability and productivity as well as reduced administrative and operational costs. Messaging Server uses committed transactions, which means that messages are not acknowledged as received until they are committed to disk. This reliability feature protects mail messages from loss and corruption. Additionally, the Message Store is built around a custom-designed database that employs a write-once data store and a two-level index to achieve excellent performance and data integrity.
