In Outlook XP, there are several folders that have AutoArchiving turned on, by default. These folders, and their default archive periods are: Calendar (6months), Tasks (6 months), Journal (6 months), Sent Items (2 months), and Deleted Items (2 months). The Inbox, Notes, Contacts, and Drafts folders do not have AutoArchive activated automatically. The Contacts folder cannot be set to AutoArchive and does not have an archive property.

To configure AutoArchive settings on individual folders, right click on the folder and select Properties à Click on the AutoArchive tab. Select “Archive items in this folder using the default settings” à Click OK. This must be done on each folder, not including the ones listed above, to enable AutoArchive. After AutoArchive is enabled, on each folder, you can configure each folder, or you can apply “global” settings to all of the folders.
In Outlook XP, you have the ability to configure global settings (“Default AutoArchive Settings”) for all folders. To configure these settings, pull down the Tools menu and select Options à Click on the Other tab à Click on the AutoArchive button.

Uncheck the box that is labeled “Delete expired items (e-mail folders only)” à Change the number in the “Clean out items older than” box to a 1 à Click the “Apply these settings to all folders now” button. This will configure the settings on all the activated folders in Outlook. Click OK. The AutoArchive setup is complete.
