When tracking an e-mail from within Outlook, the from e-mail address is matched unexpectedtly to a user record.

The match is unexpected because the from address on the e-mail does not match the Primary E-mail on the user record but it does match the Windows Live ID field.

Tracking e-mails should not match on the Windows Live ID field.
