Introduction to EMS for Microsoft Exchange

In Update 33, EMS for Microsoft Exchange was updated with the ability to sync booking data between Exchange and EMS (Exchange-to-EMS and EMS-to-Exchange) and to create, modify, and cancel Exchange integrated bookings using additional access points (EMS Desktop Client, EMS Room Sign App, and EMS Kiosk App).

The information herein is for Update 33 or later. If you are not on Update 33 or later of EMS for Microsoft Exchange, refer to EMS for Microsoft Exchange Install and Configuration Guide (Update 32 or prior) for information and instructions regarding your version of EMS for Microsoft Exchange.

What Is EMS for Microsoft Exchange?

EMS for Microsoft Exchange, previously known as Exchange Room Integration (ERI), is a simplified integration tool that allows enhanced integration of resources and technology during the EMS booking process. EMS for Microsoft Exchange simplifies the booking process by enabling you to easily integrate with other technologies that leverage Exchange. EMS for Microsoft Exchange also allows EMS to fully synchronize with room and resource calendars to enable native Exchange workflows. 

When implementing EMS for Microsoft Exchange, choose any of the three options: 

  • Full Feature EMS for Microsoft Exchange option – Configured with both Exchange-to-EMS and EMS-to-Exchange sync options.

  • Exchange-to-EMS Sync option – Allows users to book rooms linked to an Exchange mailbox from native Exchange applications, such as Microsoft Outlook for PC or Mac, Outlook on the web, and Outlook Mobile. Exchange will push these native bookings and updates to EMS.

  • EMS-to-Exchange Sync option – Allows users to book rooms/resources linked to an Exchange mailbox from EMS applications, and EMS will push these booking updates to Exchange.


  • Allows integration of third-party technology (e.g., video conference [VC] device or display panels) to a booking in EMS by linking to a Microsoft® Exchange resource mailbox

  • Automatically includes fixed-room resources in the room booking (e.g., collaboration devices) through the Microsoft® Exchange resource mailboxes

  • Allows integration with non-fixed resources for EMS to Exchange Sync through some of the access points - EMS Web App, EMS Mobile App, EMS for Outlook, Kiosk and Room sign (EMS Desktop Client doesn't sync non-fixed resources).

  • Provides bi-directional syncing – Exchange-to-EMS and EMS-to-Exchange

  • Allows syncing of bookings with rooms linked to Exchange mailboxes from the following EMS products: 

    • EMS Desktop Client (new as of Update 33)

    • EMS Room Sign App (new as of Update 33)

    • EMS Kiosk App (new as of Update 33)

    • EMS Web App

    • EMS for Outlook Add-in

    • EMS Mobile App
