A Work In Progress
This mobile app is severely feature-lacking. Video/audio call stability is good, although the conversation tracking for IM is poor. Im still having a hard time accepting that it doesnt support the ability to create contact groups and manage them efficiently. The app should be renamed "Skype for Business Companion", as it really relies using the desktop client for most of the features. Lots of room for improvement as Microsoft merges Skype with their Lync services.
