There are two ways to view email using the ZWC: Conversation view and Message view. Both views can use the Reading pane.
Conversation view displays your messages grouped by subject, as shown below. Because all messages in a conversation have the same subject, the subject displays only once in the conversation view pane. All messages related to the conversation are displayed, even if they are stored in different folders.
The number of messages in the conversation is displayed in parentheses in the Size column (after the subject). Each conversation consists of the original message and all replies. Conversations containing unread messages are shown in bold.
Message view is the tradition email view wherein messages are displayed based on how you sort the messages in the Inbox. For example, you could display messages:
Alphabetically by sender in reverse order, as shown below
Chronologically from the most recent
The Reading pane is the area below the messages in your Inbox.
If you have the Reading pane on, when you click on an email message, the message displays in a pane below the message header information.By default, viewing messages in the Reading pane is on.
To adjust the size of the Reading pane, click and drag the divider bar up or down.
You can toggle the Reading pane on (open) and off (closed) using the View menu.
Click the arrow next to View on the toolbar, and select Reading Pane. A check means that the Reading pane is on.
To permanently change your default view from Conversation to Message:
1. Open the Preferences > Mail tab.
2. Choose Conversation or Message from the Group mail by menu.
