We have a Business plan with 15 licensed users, then will invite perhaps another 100 collaborators (unlicensed users) as part of the various projects across enterprise. All same organization. We are an O365 shop and have integrated all licensed users with O365.
However, there does not appear to be anything but a static password for the unlicensed users. In other words when they accept the collaborator invitation they are only prompted to "create a password", there is no prompt for Google or Microsoft login.
How do we integrate an unlicensed user into O365?
