As with Exchange 2010 and Exchange 2007, you can configure how much email users can store in their mailboxes in Exchange 2013 and Excange 2016. You can configure the limits so it issues a warning when it approaches its limit, so it stops receiving email at a limit and specify how long deleted items are kept. A new feature of Exchange 2013/2016 (at least via the EAC ) is that you can now see how much mail a user has in their mailbox in graphical form, this has not been present since Exchange 2003.
