Not at all login..always showing error..need an update..as of now it's waste..

Poor job by Microsoft. This app leaves much to be desired. No video, no background or lock screen integration, ring to app does not work, cannot add contacts, etc. It makes me sad that the Skype app is much better and more feature-packed than Lync. Hope Microsoft cleans this up with a major update soon.

Great productivity tool

perfect

Very sporadic. Conversations regularly show up incomplete.

Perfect!

Very productive app.

Awesome. Works perfectly, can't ask for more.

Awesome app. Got this hooked on to our internal Lync server!

Can't connect to server in China
