Undependable and always has been – Skype for Business Review

S4B and its predecessor Lync on IOS have always been undependable and inconsistent. Its fine for an emergency message that you may need to send, but don't depend on it for being constantly connected or available to others. Some messages may come through, some may come through days later, some may not even show up at all. Also, unlike other clients, the conversations are not persistent across all of the clients. They only appear where they were received. If you have a convo on your desktop, you can't see it in your device. Maybe its the intended architecture, but with today's multi device, mobile world, that is a very useful feature. If there were better clients, I would not use this one.
