We've always been told that backing up our data is a good idea. Well, that same concept can extend to email as well. You may want to archive your email every so often, such as monthly, quarterly, or even yearly.

We'll show you how to archive email in Outlook 2013 and make it easily available in the program. Your email is stored in a .pst file. To archive email, we will be moving the email into an archive .pst file.

NOTE: When you archive your email into another .pst file, all the email you choose to archive is moved into the archive file and is no longer available in the main .pst file.

To begin archiving your email, click the "File" tab on the ribbon.

On the Account Information screen, click the "Cleanup Tool" button next to "Mailbox Cleanup."

02_clicking_cleanup_tools

Select "Archive..." from the drop-down menu.

03_selecting_archive

The Archive dialog box displays. Select "Archive this folder and all subfolders" and select a folder to archive. If you want to archive all your email, select the node with your email address at the top.

Click the "Archive items older than" drop-down list to select the latest date for items to be archived. A calendar pops up. Select a date in the current month by clicking on the date or scroll to a different month to select a date. All items older than the selected date will be archived.
