This is a widely used platform for email communication, database and collaboration management through its Domino server environment. Its latest version is HCL Notes/Domino 14.5.1 (2026).

Microsoft Outlook is a widely used email client introduced by Microsoft on January 16, 1997. It mainly stores mailbox data in PST format and is a part of Microsoft 365 Suite.
