In Exchange 2013 we can see  new feature called apps. By using this users would be able to plug in their required apps in their outlook.

Administrators can decide to enable which app to be published to the outlook client via EAC in Exchange 2013.

By default we have few apps already in Exchange 2013. In addition to that we can download apps from the office.com website for outlook which can be downloaded and pushed from exchange 2013.

Also we can use any third party apps which is compatible with outlook and can be pushed from server end.

By default we have Action Items, Bing Maps, Suggested Meetings and Everyone. This apps comes under organization under apps tab  in EAC.

You can see the description of each default apps in the below screenshots

Open EAC- Select Organization – and choose apps tab

Select Action Items and its enabled by default.

We can see the default Bing maps enabled

Also Suggested Meetings enabled

Unsubscribe

Below are the three options available like add from the office store, any internet url or any executable file.

This is one of the great feature which is introduced in Exchange 2013 and extend the information and functionality of messages and calendar items.

For Example if an email contains  the stree address bing map application offers you the tab through which you can navigate and  identify the location.

Thanks
