My primary Contacts are stored in my iCloud folder and kept synced to my Apple iCloud account. Since doing this however Outlook 2010 is having problems recognizing names when I create emails and after clicking To... the Address Book shows all the contact names but does not show email addresses. If I select a name it is entered in the To field of the email as LastName, FirstName but when I send I get an error. I end up having to right-click the name in the To field, select show Contact, then copy the email address and enter that in the To field instead of the name I selected from the address book.
