Microsoft has started rolling out a preview version of its Skype video calling and messaging service to a select group of Outlook.com users in the UK.
By merging the two products, the software giant said users will be able to add their Skype contacts to their Outlook.com address book and call them back with "just a click" of the mouse.
The functionality is initially being offered to a sample of Outlook.com users in the US and UK for testing purposes, before being rolled out to all users in due course.
The software giant announced the move in a blog post yesterday, which features a step-by-step guide about how to use Skype in Outlook.com.
"With Skype coming to Outlook.com, we're bringing two of the world's largest communications services together in one place," wrote Douglas Pearce, group programme manager of connected services at Microsoft.
"We'll gradually make Skype calling available to all our Outlook.com customers as we update the experience based on your feedback," he added.
Outlook.com users selected to participate in the preview will be notified by a pop-up within their inbox, and can use their existing Skype account to take part.
To make use of the offering's video and audio call functionality, Outlook.com users will need to download a Skype web-plug in first, but this won't be necessary if they simply want to take advantage of its instant messaging capabilities.
Windows Messenger users upgraded to Skype as part of Microsoft's retirement plans for its ageing instant messaging platform can also draw on the merger to call their contacts using a web browser or Skype client, the blog post confirmed.
"As with any new experience we build, we'll be listening to feedback from the community and welcome your comments and ideas," added Pearce.
"When the Skype preview arrives in your Outlook.com inbox, we hope you try it out and let us know what you think."
The appearance of Skype is the latest enhancement Microsoft has made to Outlook.com, since ushering it in as a replacement for Hotmail earlier this year.
The switchover has hardly been plain sailing for the firm, with many users complaining about Outlook.com's new Windows 8-like interface and how difficult the new webmail service is to navigate.
