I remember reading somewhere in the past in one of the Kopano announcements that one of the ideas would be to have a button in Outlook that launches web meetings.
I currently work in an organisation which uses Outlook and Microsoft Skype for business (i.e. lync renamed).
Typically the integration between the two is such that people move from email to chat and back to email all the time within the product.
Thefore having some sort of integration between Outlook based on Kopano and its web meetings I think would be essential to be able to capture that market.
It would mean that companies using Outlook + skype can fully migrate to Kopano and not only the email part.
