Hi,

Am working on Lync 2010 Plugin, I have a requirement to enhance the Lync Plugin to support Lync 2013 and backward capability too. Is it possible to work with both Lync 2010 and Lync 2013 ( and also Skype for Business)  with single Lync 2010 SDK ? Few blogs saying Lync 2013 SDK's will not support backward capabilities. Please suggest me on the SDK's to be used for all the above Lync versions. 

Thanks

Hi MuraliDurga,

From https://msdn.microsoft.com/en-us/library/office/jj937316.aspx

Microsoft Lync 2013 client supports all applications that reference the Lync 2013 API or any previous version of the Lync client API. However, older versions of the Lync client do not support applications built with later versions of the Lync API.

Based on my understanding, the Lync 2010 SDK might be able to work with Lync 2013.

My apology if Im wrong about this, Im not familiar with Lync Client SDK.

To ensure you get better support, you may post the question in the Lync Client Development Community. They will be able to help you in resolving this issue.
