Skype 6.1 for Windows Desktop is available for download with Outlook Integration. Now it's really convenient to send a Skype instant message, start a free Skype to Skype call, or make a call to any mobile or landline - all within Outlook.
Microsoft has integrated Skype and Outlook to display contacts' online status, contact information and mood message within the Outlook contact card.
When you want to contact anyone in your Outlook contact list who is already on Skype, you can instant message, audio or video call them. To do so they need to be in your Skype contacts list to reach them. When you want to call someone on their mobile or landline from Outlook, Skype will initiate the call for you. You can call anyone as long as you have their contact information in Outlook, but you don't need to be friends on Skype. You can use your existing Skype credit or subscription to reach them.
