Question
Remove an Email Address from all Mail Contacts in Exchange 2007
A default email address was added to a large group of external mail contacts.
Each has a unique email address to an email address outside of our organization that needs to be kept.
The default email address that was also added to all of those contacts has our default domain.
Is there a better way than individually opening the properties of all 1500 contacts to remove the extra email address?
Anybody know how this could be done using Exchange Management Shell?

I spoke too soon. The result of running those two cmdlets was that the list of Email Addresses was empty and email sent to any my contacts bounced with an error message indicating there wasn't a primary email address.
I needed to create a csv file with the identity and email address of the mail contacts I wanted to modify.
I did that first by running: Export-CSV -path C:\Export.csv. That gave me my list of users. All columns were deleted except for Identity, ExternalEmailAddress, and EmailAddresses. The email address from the ExternalEmailAddress field was copied to the EmailAddresses field and removed SMTP:. Now the ExternalEmailAddress column was also removed.
So my resulting csv file looked like this:
#TYPE Microsoft.Exchange.Data.Di
Identity,E
domain.
Here's the cmdlet I used modify mailcontacts based on the values in the csv:
Import-CSV -path C:\ImportModification.csv | ForEach-Object -Process {Set-MailContact -Identity $_.Identity -EmailAddresses $_.EmailAddresses}

disable the email address policy for each mail contact first
get-mailcontact -resultsize unlimited | set-mailcontact -emailaddresspolicyenabled
then update the email address
get-mailcontact -resultsize unlimited | set-mailcontact -emailaddresses $_.PrimarySmtpAddress
