Hi @Prasad-MSFT
I am trying to stop setings in Teams client to change automaticly. in Teams settings there is option to make Teams chat app for Office. I do not want to use Teams as a chat app for Office
so I remove it, but it comes back again when I restart Teams. This is not happening to all users. I have seen that there are others having the same issue with Teams but I have not seen any fix.
This causes problem with precense in Skype and Outlook.
thanks

Hi @Erro

What is your coexistence mode in your environment?

What is your problem in Skype and Outlook? Could you provide more details with us

Based on my knowledge, If your organization is only Teams-only mode, the setting will have no impact for you. If you are still need to use Skype for Business as the default for IM and calling, it recommends you check the System settings -> Apps -> Default Apps to set the IM default is what you want.
