How do I close, reopen, or discard a collection?

You can close any collection you belong to, even if you didn't create it. Closing a collection prevents people from adding new messages to it and removes it from people's list of collections.

To close a collection, click More Conversation Options icon, then select Close Collection.

To reopen a collection, from the navigation menu, select Collections. In the Show menu, select Closed, then open the collection. Click More Conversation Options icon, then select Reopen Collection

You can discard a collection only if you're the sole member. A discarded collection is removed from all lists, including other collections and Social Objects it's related to.

To discard a collection, click More Conversation Options icon, then select Discard Collection.
