Start a new private group, give it a useful name, and check who can read it. You can also add people to an existing conversation, but that choice shares its earlier messages and attachments with them.
Choose A New Group Or An Existing Conversation
Use Start private conversation with several people selected when you want a fresh group. It starts with its own history; your existing one-to-one conversations stay separate.
Use Add participant inside an open conversation when the new people should join that continuing discussion. They receive access to its full conversation history, including earlier messages and attachments.
You must be signed in. The participant picker shows people you are eligible to contact through shared chat participation; it is not a directory of every account. Blocking rules also apply when you start or expand a group.
Start A Fresh Group
A new conversation includes an initial topic. If an existing conversation has no usable topic, the composer asks you to create one: open the composer actions, choose Start New Topic, enter a clear title, and choose Create.
Your first message should explain why the group exists and what you need from its members. A short welcome with one clear next action is easier to respond to than a long history of the project.
Add People To A Continuing Discussion
First review the conversation you are expanding. Check its earlier topics, messages, images, files, and invitations. If any of that material should stay with its current audience, create a fresh group instead.
If one addition fails, earlier successful additions remain. The dialog keeps failed and unattempted people selected so you can check the error and retry those remaining. Closing the dialog does not undo people already added.
Adding a participant can reset the title to Group DM. Add the intended people first, then choose the group’s name.
Verify the participant stack and retained conversation together before changing who can read the group.
Give The Group A Useful Name
Choose a purpose people will still recognize next week. Personal favorites and mute settings can organize your list separately without changing this shared name.
The group row menu exposes title and membership controls without requiring either action during capture.
Leave When Your Part Is Done
Leave conversation removes you from the group and your available conversation list. It does not delete the conversation for those who remain.
If someone adds you again, the retained conversation becomes available again, including its earlier topics, messages, and attachments. Leaving is a membership change rather than a way to restart or erase a group.
When Someone Is Missing
The group is ready when the participant list matches your intended audience and its title explains the discussion. Continue with Messages and Replies to compose the first update, or Organize Direct Messages to set personal favorites, mute, and read preferences.
