• 40% faster access to large mailboxes, minimizing delays when multiple processes need simultaneous access.
• Improved efficiency for shared mailboxes, ensuring seamless experiences even under heavy load.
• Elimination of lock contention, meaning processes no longer have to wait, leading to smoother performance overall.

Revamped Indexing & Search: A 300%+ Performance Gain

Search capabilities have been dramatically enhanced, making it easier than ever to find emails, contacts, and other data instantly. Large organizations will experience:

• 300% faster search performance, even in high-volume environments.
