Outlook add-in

The Microsoft® Outlook® add-in works with the Desktop version to let you view the presence of your Collaborate contacts when you’re signed in to both the app and Outlook. You can also use Outlook to view and use the Collaborate app features.

For example, from Outlook, you can right-click an email in your Inbox to call or chat with the sender. When you read an email from someone on your Collaborate app Buddy list, you’ll see that user’s Collaborate presence noted with a green, gray, or red bar in the subject header. When you move the cursor over the contact’s email address, a window with Collaborate controls opens. From here, you can start a chat or make a voice or video call.

You can install the Outlook add-in when you install the app. To open the function you want in the Desktop version, click the corresponding icon in Outlook. You’ll see these options:

  • Chat
  • Call From Computer
  • Call From Phone
  • Video Call

You can also start chats and make calls with Collaborate contacts from their contact cards in Outlook.
