Notifications using first word of displayname
Currently Teams is sending notifications towards other users when they are offline or unreachable. In those notifications the first word of the displayname is being used instead of the full Displayname or just the given (first) name. In large organisations this leads to very confusing funny situations. As an example we use as displayname the last name followed by a comma and then the first name.
So at the end you get notifications like Hi Van, Van has send you a message.
