Posts and comments that users make in Chatter are retained during the entire time that a customer's applicable org remains provisioned. We reserve the right to enforce limits on:
- The number of system-generated tracked feed updates. Currently tracked feed updates that are older than 45 days and have no likes or comments are deleted automatically. The tracked feed updates no longer appear in the feed. However, if auditing is enabled for a tracked field, the audit history for that field is still available.
- The number of email notifications that can be sent per org per hour.
Chatter Browser Limits
Some third-party browser plug-ins and extensions can interfere with the functionality of Chatter. If you experience malfunctions or inconsistent behavior with Chatter, disable the browser's plug-ins and extensions and try again.
In the Spring ’20 edition of Lightning Experience on iPad Safari, check your text editors for rich text editor support. For example, check for support in a feeds publisher. If you don’t have rich text editor support—you can’t add an emoji or a hyperlink—you’re using an older, unsupported editor. Talk with Salesforce Support about bringing in the Quill editor to replace it.
Chatter Mentions Limits
You can’t mention archived groups, unlisted groups, customer groups, and private groups that you’re not a member of. If a person who isn’t a member of a private group is mentioned in a post or comment on that private group, the mention link displays as gray and links to the member’s profile page. An exception is when the person mentioned has Modify All Data permission. In this case, the link displays in blue and links to the member’s profile page. However, Salesforce security and sharing rules still apply. People who aren’t a member of a private group don’t have access to the private group and don’t see or get notified about any updates.
