Despite the obvious importance of doing so, backing up emails is actually a rather tricky thing to do. Most programs keep emails hidden away in obscure folders and, even if you are able to locate these folders, it is notoriously difficult to retrieve individual messages.
MsgSave has the ability to save individual messages or groups of messages to the hard disk, allowing you to archive them to CD. Each message is saved as a .msg file that can be opened in Outlook, but not Outlook Express, with just a double-click.
After a quick and easy installation, a MsgSave icon is left in the Outlook toolbar. Each message's file name can be constructed from whatever information you want, including the sender and subject line.
