Recent Outlook and OWA Enhancements Disappoint On-Premises Exchange Customers

Microsoft is obviously putting a lot of effort into improving the functionality available in the OWA and Outlook clients, but only for Office 365 users. It’s now got to the point where on-premises customers must be wondering where their next update will arrive. The answer may be “Never”.
