Windows Users

Your users must be using Webex Teams for Windows on Windows 7, 8, or 10 with Microsoft Outlook 2013 or 2016, Microsoft Office 365 (version 16.0.9001 or later).

In your Active Directory, you must populate the proxyAddresses field for each user, the format of the SIP address is SIP:username@example.com. Ensure that the SIP address for each user in your Active Directory matches with the Webex Teams username.

  • For users in your organization, you must register the file spark-windows-office-integration.dll using administrator privileges. You can run regsvr32.exe on the .dll file, or use another method.


    The spark-windows-office-integration.dll file is part of the Webex Teams installation and is stored in the dependencies subfolder of the folder where you have installed Webex Teams. For more information, see Cisco Webex Teams Installation and Automatic Upgrade.

    Example of how to register the .dll file using regsvr32.exe:

    Go to the directory for the dll, for example:
    c:\Users\anita\AppData\Local\Programs\Cisco Spark\dependencies
    Enter the following:
    regsvr32.exe /s spark-windows-office-integration.dll

    Example of how to unregister the .dll file using regsvr32.exe :

    Go to the directory for the dll, for example:
    c:\Users\anita\AppData\Local\Programs\Cisco Spark\dependencies
    Enter the following:
    regsvr32.exe /s /u spark-windows-office-integration.dll

    Users must restart Webex Teams and Outlook to see status from Webex Teams in Outlook.

  • For users on a free account, they can integrate Cisco Webex Teams status with Microsoft Outlook in the Webex Teams app if they are administrators on their computers. Then, they need to restart the Webex Teams app and Outlook.

Mac Users

  • If Webex Teams is the only app that users have installed that integrates with status in Outlook, then Webex Teams integrates with status in Outlook by default.

  • If users have another app installed that integrates with status in Outlook, then the user must choose to integrate Webex Teams status in Outlook. Then, they need to restart the Webex Teams app and Outlook.

Conflicts with Other Apps

  • You must only maintain one app that integrates with Outlook for status. Having more than one app integrated with Outlook can cause conflicts. When you want to enable Webex Teams status integration with Outlook, users need to quit and unregister any other instant messaging apps that they use to connect with Outlook.

Tips for Removing the Integration

  • For users on Windows, you can unregister the DLL for users in your organization or users with a free account can choose to remove the integration in the Webex Teams app. Users must restart both the Webex Teams app and Outlook.

  • For users on Mac, they can change the setting in the Webex Teams app. Users must restart both the Webex Teams app and Outlook.
