Installing the Outlook Add-In

Admin Installation

To install the Outlook add-inn

You will need to request the XML Manifest file that will eventually be uploaded and installed in your Office 365 account as a custom add-in. The XML file contains vital information that allows the add-in to link to your organization's KMS and to various other configurations. 

Office 365 has various ways to install the add-in. Detailed documentation can be found here

Recommended Approach for Deploying Office Add-ins

Microsoft's recommended approach for deploying Office add-ins is as follows::

Consider rolling out add-ins in a phased approach to help ensure your add-in deployment goes smoothly. We recommend the following plan:

  1. Roll-out the add-in to a small set of business stakeholders and members of the IT department. Evaluate if the deployment was successful, and if so, move on to step 2.

  2. Roll-out to a larger set of individuals within the business who will be using the add-in. Again, evaluate results and, if all went well, go to the next step of a full deployment.

  3. Full rollout to target audience of users.

Depending on the size of the target audience, you may want to add or remove roll-out steps.

User Installation

  1. If you want to install the add-in for one user only, you can install it via the Outlook Get Add-Ins panel:
  2. Go to My add-ins and scroll all the way down and select the Add from file option from the Add a custom add-in dropdown: 
  3. Select the XML that was given to you by the Kaltura representative.

Creating a Webcast

After the add-in is installed in Office 365, all users that were included in the add-in deployment will have the Kaltura Webcasting button in their Ribbon section in the New Meeting view.

To create and associate a webcast in Kaltura to an Outlook meeting

  • Click on the Kaltura Webcast button in the New Meeting view.
    Depending on your organization's Kaltura MediaSpace login configuration, there is a good chance that you will be asked to log into MediaSpace via your login provider.

After you login, a webcast event is created for you with the name of the meeting. If no event has been inserted, then the default name of "Webcast Event"  is given to the webcast.

By default, the webcast that is created is unlisted to ensure a seamless workflow,  Once the invite is sent to participants, everyone that has access to that KMS will be able to view the webcast. The default webcast's publishing status (unlisted) may only be changed n KMS by any of the Webcast event's collaborators.

Meeting Options


After the Webcast is created,  the invitation information is added in the meeting invitation body, for you to easily invite the webcast participants.


In the Location field, the add-in adds the URL of the meeting that has been created to make it easier for the webcast participants to find/ attend. If for any reason this isn't the behavior you want, you can always erase the location field value and change it to whatever suits your use-case.

Updating the Webcast

After the webcast is created, the association between the webcast and the meeting stays persistent and each time that you open the meeting and click on the Kaltura Webcast add-in the same webcast event is shown.

To update the Name,Time or Date

  • Update the Name or the Time of the meeting and the webcast will update automatically.
    After updated, a banner is displayed above the meeting body, indicating that the webcast has been updated.

If you want to edit any other information you will need to login into the correlating KMS and update the information there. The Name, Time and Date will always be updated to show the date in Outlook. If you update any one of these fields in KMS and then open the meeting and the add-in, the Date, and Name will be updated to the values in the Outlook meeting

Add-In Webcast Panel


The following lists the various configurations and information shown in the Kaltura add-in panel:

  • Name - This is the name of the webcast as shown in MediaSpace, This name stays in sync with the meeting name.
  • Edit Webcast - This is the link to MediaSpace, You may want to go and spice up the webcast appearance by adding any one of various options such as Presenters, Thumbnail, etc.
  • Webcast Page - This is the link to where the participants can view the webcast in MediaSpace.
  • Publishing - the publishing configuration of the webcast. By default the status will be unlisted unless configured otherwise in MediaSpace. Clicking on the Change button opens a browser to the webcast page where you can change the publishing configuration.
  • SIP User - If your organization uses Kaltura VCI (Video Conference Integration), use the Generate button to generate a SIP User that you can add to your video conferencing tool. This configuration allows you to broadcast your webcast using the video conference as the video source. If for any reason you want to change the SIP User for that webcast, you can do so by clicking on the Regenerate button that is displayed after the SIP user has been generated.
  • Primary URL - If you want to stream to the webcast using an external encoder, use this URL to configure the encoder to properly stream the webcast.
  • Secondary URL - Use this URL as the secondary stream URL for encoders that support it.
  • Stream Name - Configure the stream name in the encoder to properly stream the broadcast.

Remove Event

You can remove the association of the webcast to the meeting by clicking on the Remove Event button. The Remove Event button DOES NOT DELETE the event, it only removes the association of the webcast in MediaSpace to the meeting and closes the add-in panel. The information added to the meeting body and location are not deleted so as to not harm any content that might have been added.

The next time you click on the Kaltura Webcast add-in, a new webcast is created and associated to that meeting. 

Launch Webcast

If the Webcast Application has not been previously downloaded, the Launch Webcast button opens a browser with the Webcast Application download page.  In addition, for those that have the Webcast Application installed, the application opens with the correlating webcast ready to start broadcasting.

Meeting Attendees

When sending the meeting invite to attendees that have the Kaltura Webcast add-in: if the attendee clicks on the Kaltura Webcast add-in while viewing the from the meeting in Outlook, you can then see the webcast right within Outlook. In addition you also have the ability to join the webcast from within MediaSpace which is the preferred viewing experience.
