Limits to synching Outlook Contact information with Outlook.com

I have lots of contacts in Outlook and I’m switching to an Outlook.com account.

I’ve noticed that many of the advanced contact information fields that are available in Outlook are not available in the People section of an Outlook.com account.

For a couple of contacts, I’ve filled out these fields.

What will happen with the information in these fields when I move the contacts to Outlook.com?
