Working in a global organization means there is a need to support diverse cultures and different languages. Desktop images with the desired Windows Operating System, core productivity applications and line-of-business programs can be built using a “base” language, typically English. On top of it, Multi-Language User Interface pack (MUI) extends the product to enable support for languages other than English, such as for Office 201x users.
As Lync 2013 / Skype for Business 2015 (Sfbc) is part of Office 2013 Professional and …
… higher editions, the ability to choose a different language for the user-interface UI like in Lync 2010 under Options / General is no longer available.
Instead, one way to accomplish this is to use Outlook / Options / Languages and pick the desired language from already installed language packs. Upon restarting all currently running Office family of products, including Lync 2013 / Sfbc, all applications in the suite will automatically use the specified language for the UI, and optionally Help-System if available.
Nevertheless, be aware that the number of options available in the Lync / Sfbc UI for languages other than US-English are not the same and rather limited. Why is this the case is unclear; perhaps it is “by-design”?
