have introduce a quota in ShareFile but that is really misleading.
A quota should be a "hard quota" so we can control user's usage. Daily alert alone is not enough especially if you have some user that misused the ShareFile by putting non business data. (we don't even know this since we cannot see the files that user stored)
Hard quota also important for hybrid implementation since the allocated size by our System Administrator is the only size we have available to share to all users.
