I am having issues with contact email address not working in the "TO:" field
when trying to send email. NONE of the email addresses show up when I click
on the "TO:" in the email window. All of my email addresses show up on their
respective contacts when I look them up in the contacts section of Outlook,
but they don't show when I attempt to actually send email to them.

I get this error when I add a name to the "TO" field and then double click
on that name: "Cannot perform the requested operation. The command selected
is not valid for this recipient. An invalid ENTRYID was passed in."

I do sync with an iPhone/iTunes & MobileMe...

Any suggestions?
