I'm evaluating SharePoint 2010 and have been trying workspace, which seems to work ok. The only strange thing I've notices is I get a credentials box pop up saying it's trying to connect to "blugro4relay.groove.microsoft.com".
What is this connection for, is it needed/can it be switched off.
The box is asking for my own local credentials so may be being forced by a local proxy server and entering them allows Workspace to work fine.
I'm just curious/concerned about this connection and I can't find any information about it.
