Support - How to back up your Email

Email cleaning and backups: while keeping all your email from years past may be helpful for future reference, it is always a good practice to clean out those trash bins and create a backup of old mail to be stored on disk. These backups can be lifesavers if your disk drive fails or a system is wiped out (knock on wood). The process to create a backup of your email files depends on the email software you are using. If you use the Outlook calendar, you may also choose to back it up as well.

Outlook

Open a mail folder, then go to File, Archive. This will allow you to create a .pst file that can be saved to disk. You may also want to clean out your Trash folder by going to Tools, Options and clicking on the Other tab. You may also choose the Auto Archive button, which will give you the option of cleaning out your Trash folder.
Creating a backup copy of a folder. On the File menu, click Import and Export. In the wizard, click Export to a file, and then click Next. Click Personal Folder File. Follow the rest of the steps in the wizard.

Outlook Express

To compact and backup email folders select an email folder. On the File menu, point to Folder, and then click Compact. To back up the folder, find the folder file, and then copy it to a backup folder, floppy disk, or network drive. Outlook Express e-mail folders have a .dbx extension (for example, "Sent Items.dbx").
