The conversation history is cluttered and is difficult to read in Communicator 2005 when Communicator 2007 is used to initiate a conversation and when Multiparty IM is used

Consider the following scenario in Microsoft Office Communicator 2005:

• There are three participants: User A, User B, and User C. User A is a Microsoft Office Communicator 2007 client. User B and User C are Communicator 2005 clients.
• User A initiates a conversation with User B.
• User B invites User C to join the conversation by using Multiparty IM (MIM).

In this scenario, when User C receives a message from User B, both User A and User B are indicated as being the sender of the message instead of User B only. Therefore, the conversation history is cluttered and is difficult to read. It is difficult to determine who actually sent the message.
