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. Requires .NET Framework 2.0 to be installed.
*Update (Feb. 23, 2012): Unfortunately for current users and future downloaders, but quite fortunate for myself, my company has migrated from Lotus Notes to Exchange (they finally saw the light). As such, I no longer have a Lotus Notes environment to develop in. Moreover, I no longer have any personal need or desire to further the development of this tool.
I am happy to hand the project and code to anyone that wishes to continue the development of the tool. I do not plan to make any updates/enhancements to the current version (1.7.2) so any current bugs will not be addressed by me.
