Want to clean up your Chatter inbox? You can archive private conversations to remove them from view.
📱 On the App (iOS)
Tap on Chatter
Swipe left on the conversation you want to remove
Tap Archive
📱 On the App (Android)
Tap on Chatter
Long-press on the conversation
Tap Archive
Note: Archiving removes the conversation from your view only — it doesn't delete the messages or remove the conversation for other participants.
