Comparing Microsoft Lync vs Skype is like comparing apples to oranges. Because your business is unique and nobody except you can decide, which is better for your company. But we can add some fun to your research and suggest some new comparison parameters.

Ok, now let's compare the UI. Looks like Microsoft Lync has more user-friendly interface than Skype because it's bigger. At least on our screenshots


To compare the popularity of the solutions we counted how many alternatives people search for each of them on the Internet. And it turns out that Skype is more popular than Microsoft Lync

Looks like Skype was recently more active than Microsoft Lync (at least in our news). We also found some news, in which Microsoft Lync and Skype meet head to head:

2014 - Skype 7 refocuses on chat - a new advantage over Microsoft Lync


Skype has introduced new versions of its desktop clients: Skype 7 for Mac and preview of Skype for Windows now share the same design. The Skype redesign mimics Skype on mobile and will definitely take some getting used to on the desktop, but once you grow accustomed to the big aesthetic changes, the small functional ones are what really impress. For instance, now in your chat window you’ll be able to view shared image files instantly in-line once they download, instead of having to click a little icon to view or preview them. The Windows versions has increase spacing between your contacts list and your chat and there are message previews for things you haven’t read yet, so you can get a quick look without even switching between chats.

2013 - Microsoft connected Lync and Skype


Almost 300 million people around the world use Skype. This is a very large customer base, that's why many companies add skype-address to their contacts in order to offer customers a convenient communication channel. But in large companies using Skype at the workplace - doesn't fit the corporate security policy. Therefore, the integration of Skype with Lync communication server can become a breakthrough for deploying Skype in large companies. And thus Microsoft can get a significant competitive advantage over Cisco, Avaya and other enterprise communication vendors. That's was the main reason why Microsoft acquired Skype for a lot of money.


So now Lync (or Lync Online in Office 365) users can add Skype contacts to their contact list, see their online status, chat and call them. The same actions are available for Skype users.

What is not implemented yet: video calling, conferencing, support for Skype mobile apps. Microsoft promised to add these features later.
