  4. Rename the file to <username>.old, and then press ENTER.

    NOTE: If you are using a personal certificate, you should export it before renaming your .pwl file. If you do not do so, it may be unavailable when you send e-mail. For more information, see the following article in the Microsoft Knowledge Base:
