Tony Redmond just posted this great write-up on his views and details on Microsoft Teams, which is Office 365’s answer to Slack. I’ve been using Slack for over a year and a half and look forward to working with MS Teams and comparing the two soon.
Note: Microsoft Teams is in preview release only at this point, general availability is expected in early 2017.
