Summary

This hour introduced you to the new Unicode message store format, which provides support for many of the character sets used worldwide. A side benefit of Unicode is the ability to store more items in your personal folders than the ANSI format used by older versions of Outlook. Because the Unicode format doesn't have a file size limitation, you won't have to worry about losing data if you let your personal folders get too large. You also learned how to set up a personal folder and move your folders between personal folders.

In addition, this hour explained what the different files Outlook stores on your hard drive are used for and which ones should be backed up. It also included some troubleshooting tips to try when Outlook misbehaves.
