We have Office 365 Enterprise Level one. We currently use it for the SkyDrive and the Sharepoint. However, all we do is load up documents to the Sharepoint and simply view the files and occasionally make edits. What are you experts using the Office 365 suite for? I am looking for other popular ways to utilize what seems to be a very un-utilized tool.
I notice there are apps that I can add. Also, are there any client-side apps that would benefit the user or make their experience better?
