Visibility of User and Group @Mentions in Chatter
When you @mention people or groups in a Chatter update, anyone who has access to the update can see the post and all comments.
| Available in: Salesforce Classic and Lightning Experience |
| Available in: Essentials, Group, Professional, Enterprise, Performance, Unlimited, Contact Manager, and Developer Editions |
This table describes where you can find posts and comments that mention people, public groups, and private groups. You can’t mention unlisted groups nor private groups with customers.
| If the post was made on | And mentions | Then these people can see the post and comments |
|---|---|---|
| A person’s profile | Other people | Anyone with access to the person’s profile. |
| Public group | Anyone with access to the person’s profile. | |
| Private group | Anyone with access to the person’s profile, even if they’re not a member of the private group. | |
| Public group A | Other people | Anyone with access to public group A. |
| Public group B | Anyone with access to public group A. | |
| Private group | Anyone with access to public group A, even if they’re not a member of the private group. | |
| Private group A | Other people | Members of private group A. |
| Public group | Members of private group A. | |
| Private group B | People who are members of both private group A and private group B see this mention in both group feeds. People who are members of private group B but not members of A don’t see the mention or receive any notification for it. | |
| Unlisted group A | Other people | Members of unlisted group A and users with the “Manage Unlisted Groups” permission. |
| Public group | Members of unlisted group A and users with the “Manage Unlisted Groups” permission. | |
| Private group B | People who are members of both private group B and unlisted group A, or people who have the “Modify Unlisted Groups” permission. | |
| Record detail page | Other people | Everyone who is following you or this record and has access to the record sees your post in their What I Follow feed. |
| Public group | People with sharing access to the record. | |
| Private group | People with sharing access to the record, even if they’re not a member of the private group. |
The visibility of posts and comments depends on sharing access to the post. Anyone with access to the original post also has access to all subsequent comments on the post.
