How to backup Outlook data files

Outlook stores emails, contacts, and appointments in single files called personal storage folders, *.pst. The location of these files is a bit obscure and means they are often missed from backups of your PC. Also as the files are often locked they can be skipped when you do a backup!
So where are these files? Well it depends on your operating system and version of office. But you can find the locations easily;
- Close any messaging programs such as Outlook, Microsoft Exchange, or Microsoft Windows Messaging.
- Click Start, and then click Run. Copy and paste (or type) the following command in the Open box, and then press ENTER:

- Control Panel opens.
Note If you see the Pick a category screen, click User Accounts, and then go to step 3.
- Double-click the Mail icon.

- Click Show Profiles.
- Click the appropriate profile, and then click Properties.
- Click Data Files.
- Under Name, click the Personal Folders Service that you want to back up. By default, this service is called Personal Folders. However, it may be named something else.
Note If you have more than one Personal Folders Service in your profile, you must back up each set of .pst files separately.
If there are no entries called Personal Folders and you have not yet stored any information such as messages, contacts, or appointments in Outlook, you probably have not yet enabled the Personal Folders Service.
