Import PST e-mail from Windows Vist Outlook to Windows 7 Outlook

If I import the file outlook.pst which I made in Windows Vista into Outlook in Windows 7, it is put into the folder "large files' and when I tried to open, it imported my addresses, but it will not open to release my e-mail from Vista. I get error message "Cannot open this item. Outlook blocked access to this potentially unsafe item." How to I open it. It is NOT unsafe; I scanned it for viruses.

Try to run outlook and then from the top menu bar, select File and then click Import and Export. Select the Action Import from another program or file and click Next. Select Personal Folder File (.Pst) as the import file type and click Next. Click Next and choose a folder in the dialog box, in the emails to be imported. Complete the process of finishing off. There are other ready to use tools that can help you out.
