Connections is social enterprise software, and it does that well.
Connections is enterprise collaboration software, and it does that well.
Connections is not so good at personal/small team collaboration, where O365 and G-suite excel....and have the market share.
Conversely, O365/G-Suite do not function well as social enterprise or enterprise collaboration software.
Therefore, please develop meaningful integration with other collaboration platforms so that instead of Connections competing with O365/G-Suite, they become enhancements of each other.
