The Outlook.com, Windows Mail and Calendar app teams which were initially part of the unified OS group are now part of the Applications and Services group under Qi Lu. Specifically, they are part of the Outlook team in that group. I'm hearing this could result -- at some point -- in the Windows Mail and Calendar apps, which were built by the Windows 8 team, being replaced with the Outlook app that is now available for Windows RT. The thinking? Fewer mail clients means less confusion. I vote yes, even though the Windows Mail client got a lot better with Windows 8.1. Update: If and when this happens, Outlook will have to become a Metro-Style/Windows Store app, I'd think. Right now, it's a Desktop app (even on Windows RT).
