Attachments Processor will help you to save space in PST files or in a mailbox on Exchange Server, it also offers greater opportunities for automatic attachment management. The program can automatically extract attachments from incoming messages to save them to hard disk - they are replaced in a message with a link to the file, or a text description, pack attachments in the outgoing messages and unzip archived attachments in the incoming ones.
