You can send instant messages in Groove to contacts as well as members of a workspace.
If you use Windows Messenger or Communicator, you can integrate the contacts you have set up in those applications with your contact lists in Groove.
Groove maintains your instant messaging history in a list that you can use to read messages, reply to messages, and find specific text in a message.
With the Groove Chat tool, you can converse online with workspace members. You can format text in the Chat tool, draw chat messages in ink, or use the audio chat feature to speak with other workspace members.
