All your data are belonging to MS.
Truly scary chit, to me. Any company that loves using MSs convenient data handling apps listed above deserves what it will, someday, get.
My company recently switched from a "roll-our-own" mix of old-style open-source applications to Office 365 for mail, calendar, messaging, chat, online-storage, etc. It's been a royal PITA both for the users and for us in IT/Support. Things are broken every day, and the list is growing, not shrinking.
Just now, Microsoft is not one of my "They Get It Right" vendors.
