Outlook archive files are stored on your main computer in a file with the extension '.pst'. In Outlook, your archive files will be listed under 'All Mail Boxes' and under 'Archive Folders'.
Outlook will AutoArchive Mail, Calendar entries, Tasks, etc. after a specified amount of time. At present we recommend that you autoarchive information after six months. If you find that your Exchange mailbox is filling up, you can adjust the autoarchive settings (Tools...Options...Other...AutoArchive).Posted by dcoates at October 27, 2005 04:30 PM
