  1. Right-click the link, and click Properties on the shortcut menu.
  2. On the Link tab, click Change Source.
  3. Click to select the file, and then click OK and OK.

The item opens in the current version of the Office program.

NOTE: This fix only works while the Outlook item is open. If you close and reopen the Outlook item, or send the message to another computer,you will receive the error message again.
