So far I’ve been asked from peers members and seen myself that there is not support to SYNC the Calendar between Office Outlook 2007 and Groove 2007. Let say if you have your existing Calendar in Office Outlook 2007 then you can import is to the Groove or vice versa. This is really killing but I’ve found a 3rd party tool which claims they support this feature. I’m evaluating the product and soon as I’ll do my hands-on it . I’ll update the blog.
