Issue removing secondary SMTP address from Mail Contact in Exchange 2010

     We have a user that was setup as a mail contact with his personal email address.  They also added an internal secondary SMTP address using the companies domain.  I received a request to create a new company account for that user.  I went into the contact information in Exchange 2010 and tried to remove the secondary domain email address so I can now use that for the AD account.  When I click the delete button it does go away but once I click the Apply button it shows backup.  I don't want to remove the contact just yet as I want to make sure they are ok with us removing it completely.  I added another SMTP address and was able to remove from that contact with no issue.  Any idea on why I can remove an SMTP address from a contact?  Thanks.

use Powershell to disable updating email address from recipient policy for all such contacts.
Lets say your contacts arer residing in any perticlar OU.
Then use below powershell commad from exchange shell:
Get-MailContact -OrganizationalUnit "domain.local/OU" | set-mailcontact
-emailaddresspolicyenabled $false
Then remove secondary SMTP address from contact through EMC.
You may use ADModify.net to strip off the secondary SMTP addresses assigned to contacts.

This due to  "companies domain" was part of Default Email Address Policy. To remove the secondary SMTP address, uncheck the "Automatically update email addresses based on email address policy on Email-Addresses tab of the mail contact
