The original reference to Flow was discovered by @h0x0d and it seems that based on the app’s description, it is meant to be used as a light-weight email app as an alternative to Outlook for users looking for a quick and easy way to reply emails. “Use Flow with anyone, it’s email: Reach anyone with an email address and all conversations for you and others are also in Outlook. Together, you can use Flow and Outlook interchangeably to participate in the same conversations.”
The description also suggests that the app will display emails like you would expect from a messenger app. “Fast, fluid, natural conversations: No subject lines, salutations, or signatures. Flow is designed for fast, light-weight conversations in real time.” Now we can only imagine how clogged up your inbox can get with so many conversations.
However the app claims that only conversations started in Flow will show up in Flow, and will not cross over into your regular inbox thus keeping things a bit neat. Unfortunately when ZDNet’s Mary Jo Foley reached out to Microsoft to comment, the company claimed they had nothing to share about Flow, so we guess we’ll just have to keep an eye out for it.
