In these days of e-mail overload, it is often very difficult to keep up with the heavy stream of mail -- let alone find a specific message when you don't remember who sent it and only vaguely remember the words the sender used. These circumstances make it hard to use search techniques or even advanced search software. But Microsoft Outlook users can turn to NEO Pro from Caelo Software to further organize your mail.

NEO Pro supplements Outlook e-mail with an alternative interface that indexes every message and keeps track of your messages for you.

Unlike standard search tools, NEO Pro differentiates between the words in the e-mailer's address, subject and message body. So when it organizes your mail, it can place it in special NEO folders -- allowing you to find it, based on the way you really think. If you know the message came in yesterday, look in the yesterday folder.

NEO Pro prebuilds common folders including yesterday, today, last week and last month, so if you have a vague idea of when you sent or received a message, you can find it in a snap -- even if you keep lots of Outlook folders. Each of the time-based NEO Pro folders knows which Outlook folder holds the message.

Let's say you want to find all the messages sent to or received from your friend, Michael. You'd go to the "Correspondents" section, where you'll see a special NEO Pro folder for Michael along with those for the other individuals with whom you've corresponded -- even if you have not created these folders in Outlook. This doesn't keep you from finding the message in the proper Outlook folder. It just makes it quicker to find. And it helps separate your personal correspondences from your subscriptions.

NEO Pro costs $79.95 at www.caelo.com.
