Windows Explorer will open to your Outlook data folder. Select your data file (probably Outlook.pst), and then click the Open Folder button (version 2007) or the Open File Location button (2010). Once you’re in the dialog box, click the Data Files tab. For version 2010, click the File tab, and then select the Info option in the left pane, followed by Account Settings, and Account Settings again. To open it in Outlook 2007, select Tools, Account Settings. You can do so in the Account Settings dialog box. Getting to the Account Settings dialog box in Office 2010 requires you to click an Account Settings button, which pulls down a menu with only one option: Account Settings.So you need to make sure that you’re backing up your Outlook data. And since Outlook handles its data files in its own unique way, your regular backup routine may not be protecting its data.
If something destroys or corrupts that file, you’re in trouble. You keep a lot of information in your Outlook data file–including your email messages, your contacts, and your appointments.
