Question about Outlook Express

Hi guys,

First, thanks in advance for any help / advice.

I just did a clean re-install of my laptop.

1) WLM 2012 works fine for mail functions, but calendars do not sync,.

They are visible in outlook.com and in the data folders, I see my original calendar data files.

How do I link the current calendar data file to the old calendar data files?

2) How do I identify which of my folders are the actual current data files?

Even the old data files appear to be being accessed on a regular basis, based on last modified dates.

Thanks!
