Allowing deletion of private chat threads is on the backlog.N. Reginald supported this idea ·N. Reginald commented
We just started testing Teams since we heard that Skype for Business is scheduled to go away soon. We are extremely concerned that we are prevented from configuring the service to prevent the capture of chat histories. We see that there is an option to delete chat history after 24 hours, but this isn't ready for prime-time apparently. Unfortunately, the capture of ANY chat history (even for 24 hours) puts our employees into a difficult legal position. What is Microsoft going to do about this problem? We haven't seen any official response to this thread other than the totally off-base response by Suphatra. Can someone post a better reply with information about what Microsoft intends to do? We cannot deploy Teams unless this problem is solved.
