Email addresses include trailing "(E-mail)" - how to remove?

[peter]

Hi,
We use Microsoft Outlook 2000, and Exchange Server 5.5.

When I select email recipients out of contacts, the name always gets
suffixed with the text "(E-mail)".
For example, if the file as name is "John Doe", then Outlook will
always use "John Doe (E-mail)" when I send an email.

Is there a way to stop Outlook from appending this extra text?
(Note - we use Exchange solely for email, not for faxing etc. So if
there is an Exchange setting, that would be fine also.)

Thanks,
Peter
