I'm running Outlook 2007. I ended up exporting my entire contact list to a
CSV file and re-importing it all. Took care of the issue.

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?
