Outlook
Currently, the Outlook Add-In is not available on meet.opentalk.eu.
For administrators with an on-premise installation only: The Outlook Add-In also requires a server installation, the instructions for this can be found under Server Configuration
Installation
Add-ins are linked to an email account and synchronized across applications via the Exchange server (e.g., Outlook on Windows, Outlook Web). There are multiple ways to connect the OpenTalk Outlook Add-In with Outlook, depending on your configuration:
The actual Outlook installation of the Add-In is usually done by the administrator of the Exchange Server.
Create OpenTalk Meeting
To call the OpenTalk add-in, go to the calendar and create a new meeting.
Depending on the screen resolution or window size, you will see the OpenTalk Meeting
button in the toolbar or in the additional options (3-dot menu):

On the first call, you will be prompted to log in to OpenTalk and must confirm that Outlook is allowed to access your data.
Afterwards, the usual Outlook meeting window will open, and you will see the various OpenTalk options on the right side.

First, enter the title of your meeting and, if necessary, a description, and then select additional options in the OpenTalk section. You can directly select participants in the OpenTalk section.
To finish, click Create
to create the meeting in OpenTalk.
Features
Currently the Outlook Add-In supports creating, editing, and deleting meetings. When creating or editing meetings, the following options are available:
- Title
- Description
- Start and end time/date
- Participants (including user search)
- Meeting details
- Waiting room
- Shared folder (if available in the OpenTalk installation)
When a meeting is created, participants are invited via an email sent by Outlook. Additionally, we insert a link to the meeting room in the description and in the location of the meeting. The link in the location allows for quick access to the meeting from the calendar view without having to open the event details.
Known Issues and Limitations:
- All-day meetings are currently not supported (this feature is still in beta in the Outlook API).
- Recurring meetings are currently not supported (Microsoft’s implementation of recurrence is non-standard).
- Outlook events must be deleted manually when a meeting is canceled, but we make the user aware of this.
- Currently only available in English.
- Template generation currently only with an invitation link.
- "Add online meeting to all meetings" function:
- To avoid confusion, we strongly recommend disabling the "Add online meeting to all meetings" feature in Outlook. This default setting automatically creates a Teams meeting and adds a "Join Meeting" link to every Outlook event. For obvious reasons, this can be confusing when scheduling an OpenTalk meeting. To disable this setting:
- Go to Settings > Calendar > Events and invitations.
- Disable the "Add online meeting to all meetings" toggle.
