Define a default view for the folder. If the mailing list is used to facilitate discussion on a certain topic, then a view that organizes messages by Conversation Topic might be appropriate. Send the message to subscribe to the list. Every folder has a SMTP address. If the folder is hidden from the Global Address List, you can add it to your Personal Address Book from the Administration page of the folder properties.
Some list servers require the subscription request to come from the person subscribing to the list.
In these cases, it is necessary to send the subscription message on behalf of the public folder. When composing the subscription message, select From on the View menu to expose the From field on the note, and enter the public folder's address. If the folder is hidden from the Global Address List, you can add it to your Personal Address Book from the Administration page of the folder properties. If you later decide to delete the public folder, make sure you unsubscribe it from the list first. Otherwise, non-delivery reports will be returned for all messages sent to the folder, and the list owner will be forced to intervene to unsubscribe it.
