Considering the following scenario:

  • User A and user B are using the Microsoft Skype for Business on Mac client.
  • User A sends an instant message (IM), for example, "test1" to user B, and user B does not respond.
  • After several minutes, user A sends another message, for example, "test2" to user B, and user B still does not respond.
  • User A sees a conversation with user B under the Chats tab in the Skype for Business on Mac client. The conversation shows messages "test1" and "test2."
