Here ya go as promised:
Lotus Notes to Google Calendar tool | Get Lotus Notes to Google Calendar tool at SourceForge.net
I have been using release 0.9.9.r5 for about 6-7 months with 0 issues.
Just upgraded to 0.9.9r8 and it runs fine, will try 1.0 later on today.
This is a true 1 way sync. I have it setup to sync every hour.
Couple things I have found.. Set this up to run as administrator if you are using vista/7 as it writes to a settings file.
Do not add reminders on holidays (Default is to remind you in lotus notes 8.x) else your goign to get a nice reminder on your phone every single friggin holiday.. drove me nuts until I went and removed all holiday notifications from my notes calendar.
I don't sync against local mail, I go directly to the server.. that way anything that hasnt replicated yet will show up and I dont need to have lotus open for it to sync which is key..
Enjoy and feel free to PM me any questions.
