I. Intro

A topic group allows you and other members to exchange ideas on topics you're interested in and engage in meaningful discussions without being distracted by irrelevant information.

In a topic group, you can create topics, as well as reply to and subscribe to topics you find interesting. Replies within the same topic are grouped together, allowing you to view the entire discussion by opening the topic.

II. Steps

Create a topic group

Click the New icon above the search bar and select New Group.

To close a topic, hover over a topic, and click the More icon > Close Topic > Close.

III. FAQs

Can I invite someone outside of my organization to join a topic group?

Yes, you can. You need to add the other party as a Lark contact first, and then select them from the External Contacts list when adding group members.

When you add an external contact as a group member for the first time in an internal topic group, a new external topic group will be automatically generated. The new external topic group and the original topic group are two independent group chats, and there will be an External label next to the new group's name.

After inviting someone outside of my organization to join the topic group, will the original topics in the topic group be automatically synchronized to the new external topic group?

No. You can forward the original topics in the topic group to the new external topic group.

Can I view the threads I have participated in within the topic group in my filters?

Yes. Click the the Filters icon to the left of Chats to view filters, then click Threads & Topics.
