Groups on WP sync to Outlook.com

[theefman]

Wonder if this is a new feature, I just noticed that groups I previously created on my WP appear under People on outlook.com and vice versa, new groups from outlook.com appear on my WP. The default outlook.com groups dont seem to sync though until you add a contact to them. I recall some people have asked for this in the past, did I miss this being reported or is this new?
