Borderline "OK" – Microsoft Lync 2010 for iPhone Review
The app does the job, but lacks support for the big screens of iPhone 5 and newer. As a result you can't see the conversation because the keyboard takes up all the space. The GUI is poor, no push notifications like every other app. Poor presentation but allows communicating with colleagues. Therefore it's borderline ok.
