Got no replies, and search did not turn up any results, so I crossed my fingers and tried my own solution and it worked. For any who also have this situation, here's what to do... In calendar, click FILE, then IMPORT EXPORT, FOM ANOTHER FILE, PERSONAL FILE (.pst), then select ARCHIVE folder, then CALENDAR. (I had to "browse" for archive folder because the default location did not have it.) I chose to not import duplicates to ensure I only imported what was missing. It Worked!
