With the coming version of Exchange, Microsoft has introduced the use of ‘web app’, code name Agave.
These applications are also available on SharePoint or on Office client (especially Outlook 2013).
The idea is to provide to the users additional features to assist them in their day to day work, such as find direction to go somewhere, create appointment on their calendar…based on information received through email.
For example, you may receive an email with appointment and location details. So, until now, you were obliged to use your favorite Maps service to find the direction, go to your calendar to create the appointment by copying/pasting details from the email. So there was too many action to do
With Outlook 2013 and/or OWA Exchange 2013, these is now simpler to do these operations.
