New messages are received when you log on and at automatic intervals when you in within your mailbox.
To receive new messages immediately, click Refresh on the toolbar. If you have new email, it is delivered to your Inbox.
You can spot unread mail messages by looking for folders with a bold name and a number in parentheses next to the folder name. For example, Inbox (22) indicates that there are a total of 22 unread messages that are contained within conversations that appear in your Inbox.
