You can use the ExchangeClient.ListMessages method to list messages in a folder and the ExchangeClient.GetMessage method to obtain more information about a given message.

You can manipulate existing messages by using one of the following methods:

ExchangeClient.DeleteMessage - deletes a message
ExchangeClient.MoveMessage - moves a message from one folder to another
ExchangeClient.CopyMessage - copies a message to another folder
ExchangeClient.MarkMessageAsRead - marks a message as read
ExchangeClient.MarkMessageAsUnread - marks a message as unread
