How to Import OST Files to Outlook 2007

With most installations, Microsoft Outlook uses PST files to store message and profile data located in a user’s local personal folder. However, if you use Outlook to connect to Microsoft Exchange server, the application uses OST files to map message, contact and calendar information stored on the remote server. Should you install Outlook 2007 on a new computer, or need to reconfigure Outlook for some reason, you must reconnect to the Exchange server to recreate the OST file.

Step

Close Outlook and any other Microsoft Office programs that are running.

Step

Click “Start,” then “Control Panel.” Click the “Mail” icon Control Panel.

Step

Click the “Email Accounts” button. In the “E-mail Accounts” window, click the “New” link. Click and select “E-mail Account,” then click “Next.”

Step

Click the “Manually configure server settings or additional server types” option, then “Next.”

Step

Click the “Microsoft Exchange or compatible service” option, then “Next.”

Step

Enter the domain name for the Exchange server that hosts your email account. Leave the “Use Cached Exchange Mode” option checked. Enter your Exchange email user name and click the “Check Name” button. Outlook verifies your account exists on the server.

Step

Click the “More Settings” button. Enter a descriptive name for the exchange account in the text box on the “General” tab. Leave the default “Automatically detect connection state” option selected. Click the “OK” button.

Step

Click the “Next” button on the “Server Settings” screen, then click “Finish” to close the “Add New Account” window.

Step

Launch Microsoft Outlook. Enter your Exchange server password when prompted. Outlook downloads your calendar, contacts, messages and other profile settings from the Exchange server and creates a new OST file. You can now use Outlook to manage your Exchange email account and settings.
