It is important to back up your Outlook Express files regularly. Backups are important because there are a number of incidents that can cause you to lose files. You could accidentally delete an important email and be unable to recover it, for example. Your computer could be attacked by a virus or your hard drive could fail. If this happens, you will be relieved to have a backup copy of your emails and contacts.
Before you can back them up, you must locate your Outlook Express email files and folders. Depending on your Windows operating system and whether you have changed the default location, they could be in a number of locations. You may need to change your computer folder settings to show hidden files and folders, as well.
Once you have found these files, you can take steps to back up your Outlook Express data. OE allows you to back up your address book, email messages and your Internet settings. Be sure to save these to a removable device, such as a CD or thumb drive, in the event of hard drive failure or other problem that could prevent you from accessing the files on your computer.
