Since Google stopped support for the (old) APIs Roster2Outlook was using to export to Google, I've been trying to find a new way.
Sadly enough this didn't result in a satisfactory solution. Yes, I was able to export duties to Google with Roster2Outlook, but this caused more problems than solutions.
Because of the limited time I've available to work on Roster2Outlook, I have decided to stop supporting export to Google. I'll soon release a basic version that exports to Outlook or ICS. For those who still want to use Roster2Outlook and Google, you have to sync Google with Outlook or import the ICS file manually in Google. I'll also try to add support for Outlook.com, so it will be possible to export to an online calendar. You should then also be able to link Outlook.com to Google.
