I prefer to work with HCL and not with Exchange because it's easy to manage, easy to set up, and easy to migrate.
HCL Notes is a stable and scalable solution offering exceptional security features, including field-level security and encryption, and robust offline access with replication capabilities. It integrates easily with other services to enhance versatility, although some resource-intensive operations and outdated web support are noted. Users may encounter challenges connecting with non-Domino clients like Gmail or Outlook, and performance issues with large databases may slow integration with new technologies and designs.
