Shared Mailboxes not Appearing in Windows Phone 7.5

Hello,

I have successfully setup shared mailbox inside of Office 365 that allows me to receive and send email using an alias email address.

The problem I have is that I cannot read or send email from the shared mailbox from my Windows Phone (running WP7.5).

Is there a way that I set this up on my Windows Phone? I have tried adding a "new" Outlook account using the alias email address, but only the primary mailbox email arrives on the phone (primary being the one associated with the user account).

Any ideas?
