outlook contacts

Is there a way to change the way the email address is showing up in all my outlook contacts?

for example, I have 50 contacts and about 20 of them are showing the email address as just a name and not the full email address. The problem with this is, anytime i chose these contacts using the blackberry I get a "This entry has no email address" message.  It seems that the blackberry only see's the name and can't tell there is an email address behind the name.

I have changed the contact to show the email address and saved it. After I manually change email to display the email address I am now able to use that contact on the blackberry.

So is there a way to do this for all contacts in one shot, instead of doing it one at a time for each contact?

Thanks.
