Outlook 2003 – Exporting PST file
First, start Outlook. Go to the File menu and select Import and Export.
The Import and Export Wizard will start. Select the "Export to a file" option and press Next.
In the Export to a File window you can choose the file type of your backup. For regular users, we strongly recommend the Personal Folder File (.pst) format. After you have selected the desired format, press Next.
In the Export Personal Folders window, you can select the folders you want to backup. We recommend that you select your entire mailbox and check the "Include subfolders" option. This way, you will backup all your e-mail messages, your contacts, calendar, tasks and notes.
After you have pressed the Next button, you will be asked to select the path where your backup will be stored. Click on Browse and select the backup location. After that, click on Finish.
Now, the Create Microsoft Personal Folders window will open. Depending on the version of Outlook you are using, you will see different options such as encryption settings, or password protection. You can set the desired level of encryption and protect your backup with a password. When finished, press on OK.
Microsoft Office Outlook will start creating the backup file. This might take a few minutes, depending on the size of your Inbox.
