The binaries get installed under %ProgramFiles\OpenTalk\OpenTalk for Outlook . Settings are shared between the users.
  • Only for the current user In this case the Addin gets installed in the user space of the file system and Outlook and settings are for that specific user only.

Using OpenTalk for Outlook

Start Ad-Hoc Meeting

When you click this action button a new meeting room is created. You need to login to the OpenTalk Dashboard, a meeting is created and you are presented with the URLs to enter the meeting as moderator or as guest. In addition, you'll see the dialin information if you want to attend by phone. Copy the link/phone information and forward it to the other participants. You could join the meeting yourself by clicking Open Meeting button.

Schedule a Meeting

A scheduled meeting is connected to the Outlook calendar. There are two ways to schedule an appointment including an OpenTalk meeting.

From the Global Toolbar One the Addin is started you’ll find 2 new action buttons in Outlook’s global toolbar / ribbon band. Click on OpenTalk → Schedule Meeting and follow these steps:

  • Depending on the login status you are requested to login to the OpenTalk service and confirm access to some of your personal information. Once the login was successfully completed you the see a confirmation in the browser. Close the browser window to return to the Schedule Meeting dialog.
  • Now you could select one of your favorite meeting rooms in OpenTalk or create a new meeting room. (Check "Create personal favorite meeting rooms" for more details)
  • Enter the meeting title, if you use one of your favorite rooms this gets automatically filled in using the room information. If you set a meeting password the participants have to enter this in the OpenTalk lobby before joining the meeting. If you leave the password empty attendees are not required to enter a meeting password.
  • You could select the option to enable the waiting room, so your guests have to wait until you let them into the meeting.
  • Click on Next, this creates a room in the OpenTalk dashboard.
  • The title and body fields of the calendar entry get filled with all information required to join the meeting as moderator or guest via a browser or to dial in using a regular phone. The body also includes information around data protection and links to further information.

You could now proceed adding attendees as you would do for a regular invite (without an OpenTalk meeting). Once you are done click the Send button and Outlook will send an invitation to all participants. The invitation e-mail includes an .ics attachment. The recipient could double click that file to import the invite to the personal calendar. Depending on the mail client it automatically detects the invitation and you don't need to manually import it.

When you open the Meetings sections in the OpenTalk Dashboard you'll see the newly created meeting with the attendee list. Each time you edit meeting information the attendees get a notification.

From the global Calendar View

This works in a similar way

  • Open the calendar view.
  • Double click on the time slot you want to create the appointment.
  • Click on the Schedule OpenTalk Meeting button in the top area of the calendar view.
  • Complete the dialog as described above.

Edit an existing Appointment

Beside creating a new appointment, you could also add an OpenTalk meeting to an existing one. Just double click the calendar entry and click the Schedule OpenTalk Meeting button in the top area of the dialog. Follow the same instructions as this entry was created completely new (see previous section).

Cancel a Meeting

You can cancel a meeting as usual. Delete the calendar entry by right clicking on the appointment and selecting Cancel. The Addin takes care that the corresponding OpenTalk meeting room (which is also deleted) and a cancellation message is send to all participants.

Create personal Favorite Meeting Rooms

The Addin supports a quick access to your personal favorite rooms. Those could be selected from the drop-down list when creating a meeting.

To setup a new favorite you need to

  • Go to the OpenTalk Dashboard
  • Select time independent appointment from the meeting options. This turns the room into a static room, which is constantly available (e.g. for team meetings, sales presentations, webinars etc.)
  • Go to the meeting overview and click on ... for the newly created meeting. Click on favorite.

You could add as many favorites as you like. The Addin retrieves a list when initializing the dialog and provides a drop down list.

Trouble Shooting

Addin doesn't show up

Sometimes the Addin gets installed, but the action buttons doesn't show up in the ribbon band. This could happen when Outlook deactivates the Addin.

Please have a look at:

Only one action button in the ribbon band

When Outlook loads the Addin the first time (after installation) only 1 of 2 Ribbon buttons are show. You need to close Outlook and re-open, then both actions buttons are available.

Problems during installation

If the installation doesn't complete your could activate Windows Installer logging and check the log file in %temp%. The Addin installer also creates information there. Create registry entry HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer\Logging, type REGSZ, value "voicewarmup". The log file will then be written to %temp%. For details check here

Uninstall fails

In general you should check %ProgramFiles(x86)%\OpenTalk\Outlook Addin\OpenTalkInstaller.log if this shows problems.
