You can hold instant messaging conversations with more than one user. Start a conversation with one user, and then invite additional users to join.
Double-click a user in your Contact List.
Click the Expand arrow next to the user’s name with whom you are having a conversation.
Click Invite others.
Click a user (or Ctrl+click multiple users) in your Contact List, and then click OK.
You can also Ctrl+click multiple users in your Contact List and press Enter to begin a group conversation.
Each user who is invited to the conversation receives a prompt to join the conversation.
If you cannot see the list of participants in this conversation, click to open the Control Panel.
After a user accepts the invitation to join the conversation, he or she can send messages to the other participants. A user cannot see any messages that were sent before he or she joined the conversation, or after he or she leaves the conversation.
