The Difference between Lync 2013 and Skype for Business

Posted on: June 12th, 2015 by Administrator No Comments

Some people believe that Skype for Business is just Lync 2013 renamed. That’s entirely false because Skype for Business and Lync hold a number of differences among themselves. The major difference between the two is that Lync was designed keeping the enterprise in mind and Skype for Business is designed with the consumer in mind.


Split Domain: Lync 2013 allowed users to install Lync online and on premise Lync separately on Office 365 with the same SIP domain namespace. Skype for Business offers something similar, but with a few modifications such as it doesn’t work between service provider clouds or it only works with Office 365 Multitenant.

Meeting Investments: A major drawback of Lync 2013 was that the meetings expired if they were missed. They had to be rescheduled by the organizer. Now, with Skype for Business, Microsoft added an outlook plugin which regenerates meetings and keeps them alive for 1 year. Other modifications include automatic and silent retry capabilities with the meeting service.


PowerPoint Sharing: Advancements have been made to the PowerPoint sharing experience. Meeting delegates do not become aware of the presentation until it has been uploaded completely and is ready for sharing. If sharing fails, built in retry intervals are present and if the message is not sent, then the organizer is directed to use resolution which will work. These features were not present in Lync 2013.

Screen Sharing: Lync 2013 provided 2 frames per second, while Skype for Business provides 8 frames per second. The presenter is able to share standard HD video to its delegates during the meeting. As compared to Lync 2013, Microsoft has made adjustments to reduce the consumption of bandwidth by 10 times in P2P sharing.


Better Voice and Call Controls: The transfer, hold and other such voice control functions in Lync 2013 have been improved with the new Skype for Business. Furthermore, Lync 203 utilized Lynch Web App for web based conferencing. But, Skype for Business is browser based and offers faster connection with a reduced failure rate.

Server Side Conversation History: With Skype for Business, all conversion history is s tored server-side, meaning that all devices would be able to see the same conversion history. As for Lync 2013, each device showed a different conversion history, which was not good for mobile devices.

Several other minor enhancements: Windows Fabric stability was quite poor in Lync 2013, but has been drastically improved in Skype for Business.
