Will the Flow application be part of the Office 365 user tenant? Having the user account for Flow being the same user account as the other O365 apps seems like it would be easier than having the individual user making those connections. For technical people I know it seems like a non-issue. but for most of the employees that we support, they get easily confused between personal and work related accounts when it comes to Microsoft. Mostly centered around OneDrive, but for other MS products/accounts as well. Having the Flow application under their O365 account would remove the need for them having to create an account on their own.
