Increase the Visibility of Critical Information with Pinned Posts (Beta)
Ensure that your most critical information gets the best exposure
with post pinning. In Chatter group and topics feeds, when someone posts critical information,
an authorized user can pin that post to the top of the feed. The post stays in place until an
authorized user unpins it. Post pinning is available in Lightning Experience and
Lightning communities.

Admins, community managers, and group owners or managers can pin posts. Admins can also assign pinning permission. Enable Pin Posts in Feeds for your org and then assign the Pin Posts in Feeds permission to selected users.
When you pin a post, it appears twice in the feed: where it was posted and in its pinned position at the top of the feed. You can pin only the posts that were added directly to the feed. You can’t pin posts that were added through an @mention.
Pinned posts are similar to announcements with these differences.
- Announcements are available only to group feeds. Post pinning is available to group and topics feeds.
- Announcements follow a linear timeline: you post it and you let it expire; pinned posts are more flexible: you can mine your feed and pin posts from the past or the present.
- A wider range of authorized users can pin.
- You can add style to a pinned post with the rich text editor.
- An announcement expires on a set date. A pinned post stays pinned until an authorized user unpins it.
Beta Limitations
In the beta version, there’s no way to select a post to pin through the compact feed user interface.
Chatter REST API and Chatter in Apex support pinned posts.
