Currently, Microsoft Teams is a separate installation from Office 365 Business. But, starting in January 2019, Teams will be installed by default for new installations of Office 365 Business, starting with Version 1901.

I saw this on twitter this morning and I thought it was really interesting. I’ve written before about how I think the O365 stack wins when you put it up against other individual technologies.  It seems apparent that Microsoft see this as well.  Good stuff.
