Wasn't Skype for Business just a rebranding Lync after the Skype purchase ?
This one was painful with your smartphone and computer not necessarily receiving the same messages. Also I never understood how and why my status was changing/not changing automatically.
I think Teams still suffers from similar issues. It happens that sometimes I open a second teams in a separate browser to have a full chat window while videoconferencing and both chats are not always in sync, sometimes I see a message has been sent from the notification window but if I try to see the full message it never appears on that window while it does on another one.
OCS, Lync and Skype for Business are all the same (quite shitty) product.
Like in 2014 you couldn't send a message with more than 800 chars. Now imagine troubleshooting something which requires sending logs? AND this is not confirable AND the client actively bitch at you AND you can't even the know the char limit from the client.
