Performance has been and continues to be a big focus area for Teams. One main area we have made improvements in is responsiveness for the most frequent user actions of switching between Chat, Channel, and Activity. We are also focused on reducing resource consumption and application load time. More improvements are on the way.
We acknowledge the customer demand for Private Channels and have been hard at work on it. Private Channels is currently in preview with a select group of customers. We expect to release the feature to the public later this Fall, and will update here when we are starting to roll out to all customers. We appreciate all the feedback you have provided to us on this forum and thank you for your patience.
This is in the works! Fill out this survey if you want to influence the feature: https://microsoft.qualtrics.com/jfe/form/SV_esTxHdABLQxKLvn
As part of our commitment to being customer driven, we’d love your input on top features that will improve your satisfaction with teams and channels navigation, and help you be more productive in Teams.
