Well, it's been 5 years since the last release, so I wanted to propose an alternate solution for those of you eagerly awaiting mail merge support with IBM Notes 9 running on Windows, Mac OS X and Linux.
Currently, you must download the tool below to support IBM Notes 9 running on Windows, Mac and Linux. The tool is a third-party software which is a Notes DB app. It supports Notes (Standard) and Notes (Basic) running on Mac, Windows and Linux. If you are using IBM Notes on Mac or Linux you can import Excel if you first save it as a CSV file, then use the button in the app. Otherwise, you can use the button if you are using Windows. You can use the Lite (free) version, but for full features you need to purchase a license.
