It won't, since email is in fact the best data store available to most people in enterprises (especially compared to things like Sharepoint). It might finally accelerate the move away from Exchange though. Here's hoping.
I don't know about that... unless a good open-source option comes out for corporate email that matches what Outlook/Exchange/M365 offers for calendars and scheduling.
That last part is the real point of integration... then real time chat and messaging status baked in... it's hard to beat. You have services and applications that offer pieces, but none integrate as well.
In the early 2010's I think that both Blackberry and Mozilla had an opportunity to create their own competition in the space and neither did. Google is pretty close, but IMO still a much lesser experience, reinventing a new chat app every other year didn't help their cause at all.
