Not sure if this will answer your specific problem, but:
Office is handled differently than many other applications when it comes to Control Panel > Programs and Features. With most programs, you actually 'uninstall' that specific program. But with Office you have to 'change' the application. What we tend to think of as an application such as 'Word', is actually handled more
like a 'feature'. We 'turn off', or make 'not available' that feature.
So, to 'uninstall' Lync, try this:
1 - Control Panel > Programs and Features
2 - Find the Office version you are running and click on it. The menu bar should have new commands
3 - Click on the 'Change' command
4 - Select 'Add or Remove Features'. A 'tree-like' structure should appear
5 - Find 'Microsoft Lync' and open its folder
6 - Select the 'Not Available' option
7 - Finish the dialogue
While this may seem more complicated than what we're used to, it actually makes the
Programs and Features applet a little easier to navigate and manage overall. You might take the time to look at all the available features. You'll often find a cool item that isn't automatically installed for space reasons, etc. It really
allows you to customize your Office setup. It also allows many features to be set for 'install on first use', which makes the initial Office install quicker.
Just as a kindly instruction to improve interactions on the forums, technically the uninstall question opened a new line of topic. It's better to ask new topics as a separate topic so that others looking for this same question will be able to find it.
Hope this helped. Please post with a response to let others know if this worked for you.
