1. Get rid of Teams. 2. Leave Skype as is. 3. At least add customized notification sounds to IMs in Teams.
Make Teams as customizable and user-friendly as Skype for Business. Preferably, just get rid of Teams altogether and stay with Skype. Microsoft has a keen knack of screwing up things that works just fine to begin with. Microsoft Teams is too "busy." Think simple, think intuitive, think Apple. The people who design ****** software obviously have never actually used the software for the purpose for which it is designed. BUT, if you are ****-bent on going forward with killing Skype, at least give us a way to hear the IMs being received. Isn't that the point of messaging software?
