The export to .csv from WLM to import to Outlook.com contacts is simply not working.

I have mapped all the fields to match the template from Outlook.com, and then I have copied all my contacts in and rearranged them to sit under the correct fields.

It still says the .csv document is not correct, or its empty, which is untrue.

What next?  I'm not reading all the help on this topic because it gets me mixed up.

So, I await someone to help me figure out why

a)  EVERYONE has trouble, not just me.

You are forcing me to shift from WLM to MS Outlook 2016, at the same trying to adjust to Outlook.com and Windows 10.  

WLM has been my most favorite email client for many years, and far surpasses MS Outlook 2010, Outlook Mail App, and Outlook.com.  If you followed that last sentence, you get the booby prize.
