In order to get my customers over to Teams from SfB, I need that blinking capability they have today in SfB for persistent chat. They are unwilling to move. As they are shared desktop users, the fat client is not a replacement due to the maintenance at the customer profile requirement. The web client is the better option. That is roughly 2K customers that use persistent chat.
