“Flow by Outlook” as seen on the official page header is set to also be up and available on the iPhones for Apple. Just having an email address of a contact you frequently communicate with is enough to use Flow effectively. With the latest app, you can also use it with Outlook to simultaneously exchange conversations. The biggest perk of the app is that there will be no subject field or signature. Therefore, lighter conversations are set to be real thanks to the app. In fact, all conversation messages will pop up only on the Flow inbox and not your email box. Microsoft is indeed trying to change the way we see business and Flow sure will have ample role to play in the same.
