Chat app in Outlook for Mac defaults to Teams instead of Skype for Business

  • Article
  • Applies to:
    Skype for Business, Outlook for Mac

Symptom

You cannot set the default chat app to Skype for Business in Microsoft Outlook for Mac because the default value is set to another app (for example, Microsoft Teams).

Workaround

To work around this issue, follow these steps:

  1. Navigate to the following location:
    ~Library/Preferences/com.apple.LaunchServices/com.apple.launchservices.secure.plist.
  2. Locate the LSHandlerURLScheme sip under the Root/LSHandlers/Item array and verify that LSHandlerRoleAll refers to an app other than com.microsoft.skypeforbusiness.
  3. Change LSHandlerRoleAll to com.microsoft.skypeforbusiness.
  4. Restart the computer.
  5. In Outlook, hover the cursor over the contact, and then select the IM button to verify that the Skype for Business app starts.

Alternatively, you may be able to use Workgroup Manager by getting support from Apple to avoid configuring LSHandlerRoleAll on a per-user basis.
