PeoplePicker not showing email address after i have added it in Manage User Profiles - Non AD Environment

Hi There,

I have added an email address to a user in the SP Manage User Profile.

When I go to my app and search/select the user to assign against a task, no email address is shown in the peoplepicker window.

One thing, the users Display Name as "Server\Username" rather than the Display Name of Bob Smith for example.

This is a non Active Directory Environment on SharePoint 2010.

Can anyone help?

Thanks in advance!
