HCL Client Application Access (HCAA) is a small, stand-alone application that allows you to work with your HCL Notes® and HCL Domino® applications. It is supported on Microsoft Windows and Mac OS systems.

HCAA is integrated with the HCL Verse web mail client. For on-premises users, HCAA is integrated with HCL iNotes®. When you use one of these brower-based mail clients and receive an email that contains a link or button to a Notes® application, you can click the link or button to open the application in HCAA. You can also open HCAA by clicking its icon on the Desktop. From HCAA, you can open your browser-based mail client to access your mail.
