Yousaf Sajid Thanks for the updates above. As wroot said, I'm sure other client types will benefit from urgent message notifications.
The post says "Message delegation enables a user to delegate messages to another recipient when they are not available, for example while in surgery." The screenshot flow, however, shows essentially an out-of-office pop-up in the Teams client that someone is unavailable. It doesn't appear that delegation actually changes the message flow; it's just a visual alert to anyone trying to communicate with "Daniela" that she is unavailable, and that they should communicate with someone else instead. Under this model, in what it looks like to me, the communication must then be moved by the sender to a different chat stream (so the original intended recipient - Daniela - doesn't see it), rather than being auto-routed to the delegate but maintaining coherency of message flow for both the original recipient and the delegate. Can you please confirm - Yousaf Sajid - if there is any auto-routing to the delegate?
