If the methods that are described in the "Resolution" section don't resolve the problem, you can try creating a new Unicode .pst file, setting it as the default, and then importing the data from your older .pst file. For information about how to do this, see the "How to point Outlook to your new Personal Folders file" section of the following article in the Microsoft Knowledge Base:

To import the original .pst file, it must be removed from the Outlook profile. When Outlook is running, right-click the name of the Outlook data file (.pst) that you want to remove from the Outlook Bar or Navigation Pane, and then click Close <name>. If the Close command is not available, you are probably trying to remove the default Outlook data file (.pst) that is used to save your new messages. The article that was referenced earlier provides the steps to change the .pst file that's used as the default delivery location.
After you remove the original .pst file from the profile, you can import the data into the new .pst file by following the steps in the "How to import .pst file data into Outlook" section of the following article in the Microsoft Knowledge Base:
