Introduction
The Korbyt Booking Outlook Add-in lets users seamlessly search, select, and book meeting spaces and services directly within Outlook. It streamlines single, multi-space, and recurring bookings while ensuring all updates sync with Korbyt Booking across web, mobile, and Bookit.
Prerequisites
Office 365 Exchange Administrator rights are required to deploy an add-in.
Hosted link for Korbyt Booking web application V8.5.0.0 & above
Web application must be configured with SSL.
A valid manifest.xml file that consists of links of Korbyt Booking web application that will work as Outlook add-in.
Exchange Add-Ins can take up to 24 hours to show in users add-ins list.
How to Launch the Korbyt Booking Outlook Add-in
Open Microsoft Outlook on your browser/desktop (Windows or Mac supported).
Go to your Calendar and click ‘New Meeting’ or open an existing meeting invite.
On the ribbon at the top of the window, locate the Korbyt Booking icon.
It may appear under "Apps", "Add-ins", or directly as “Korbyt Booking”, depending on your Outlook version.
Click the Korbyt Booking icon to launch the add-in panel on the right side of your screen.
When a user accesses the add-in for the first time, they are directed to the ‘Find’ screen, where primary defaults are brought from the webapp settings . From there, they can either click ‘Find’ to view available rooms or apply filters and ‘Save’ them— allowing the add-in to automatically load results based on those saved preferences the next time it's opened.
The add-in will load your booking interface—starting either from room selection (for new bookings) or booking summary (Edit).

How to Create a Booking
In your Outlook calendar, click ‘New Meeting’ to start a new event.
Fill in the Meeting title, set the Start and End time, and add Attendees if needed.
Click the ‘Korbyt Booking icon’ in the ribbon to launch the booking interface.

Note: If you're launching the Add-in for the first time, you'll be taken to the Find screen to set your default preferences. Otherwise, you'll land directly on the Select Spaces screen.
Note: The attendee count used in your search includes all invitees, plus one for the meeting organizer.On the ‘Select Spaces’ screen

Participant-based services will default to the total number of attendees plus one, to account for the booking owner.
After selecting services, click ‘Next’ to go to the ‘Booking Information’ screen.

Click ‘Next’ to review your booking on the ‘Booking Summary’ screen.

Automatic Alternative Space Search
The Korbyt Booking Outlook Add-in supports an automated alternative space suggestion mechanism that activates only during the edit journey of an existing booking. This feature saves time by finding a suitable replacement space without requiring you to open the add-in manually.
When Does This Happen?
You edit an existing booking by opening the Outlook appointment.
You change the date and/or time of the meeting directly in Outlook.
The previously booked space is no longer available at the new time.
What Happens Automatically?
Outlook detects the change in meeting time and sends an update trigger to Korbyt Booking.
The system checks space availability using the same search filters you originally used (e.g., location, layout, resource type).
If the original space is unavailable, the system automatically searches for a suitable alternative.
An available alternative space is assigned to your meeting—seamlessly and without additional user input.
If no space is found, you will see a notification inside your Outlook appointment, prompting you to make changes manually using the Korbyt Booking Add-in.

How to View Details of a Space
When searching for a space to book using the Outlook Add-in, you can easily view detailed information about each space to help you choose the best fit.
Steps to View Space Details:
Open a New or Existing Meeting in Outlook.
Click the Korbyt Booking icon to launch the add-in.
On the Select Spaces screen, you’ll see a list of available spaces displayed as individual cards.
On each space card, you’ll find a “View Details”.
Click the ‘View Details’ link or icon.
