Microsoft today announced that they are rolling out Skype video calling integration in Outlook.com users from today. The roll out has begun with UK customers, followed by US customers soon and other countries later.
You will be required to install a browser plugin – available for Internet Explorer, Firefox and Chrome – before linking up your Outlook.com and Skype accounts. Once your accounts are merged, Skype call buttons will be available whenever you mouse over a contact in an email thread or instant message; simply click to call and a window will pop-up for your Skype conversation.
Enjoy Skype within your browser!
