Update (2015-01-30): With the switch to the new Google APIv3, .NET Framework 4.0 is required 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.
