    Lotus Notes to Google Calendar tool

    Lotus Notes to Google Calendar tool

    One-way synchronization from Lotus Notes Calendar to Google Calendar

    This is a one-way sync program that will sync your Lotus Notes Calendar to your Google Calendar. No installation is required. Includes many options such as automatic syncing at specified intervals. *Important Privacy Information: https://sourceforge.net/p/lntogoogle/wiki/PrivacyPolicy/ *** Information Update, September 2020: *** Recent issues with Google Synchronization should be fixed with version 1.9.2 which is available for download, now. For typical installation pitfalls, see: https://sourceforge.net/p/lntogoogle/wiki/InstallationPitfalls/ The project was not maintained since its last update in February 2015. However, since I've tracked more than 15.000 Downloads over the last 5 years and still more than 1 million Calendar API-Calls per day, I assume that the tool is still very much in use. So I decided to go back to work. More info: https://sourceforge.net/p/lntogoogle/wiki/Home/ Donations appreciated
