Original Title: WLM 2012 Contact replacement.

With the imminent loss of Outlook.com access via WLM 2012, will this also mean that the Contacts listing will be lost? I use WLM for two other email addresses so the Contacts listing is important.

Alternatively, can I delete this list from WLM only, leaving it unchanged and in place on my Outlook.com account which I can manage from the W10 Mail app and from the web. I could then install a simple email address book for use in my other WLM controlled accounts.

Note: I would happily change all my accounts to the W10 Mail app but it has one serious deficiency ... no multiple Storage Folder possibilities. Is this going to be a feature?
