Here is a handy script to remove obsolete proxyaddresses from all mailboxes.

foreach($i
in Get-Mailbox
-ResultSize Unlimited)
{
　 $i.EmailAddresses |
　　　 ?{$_.AddressString
-like ‘*@domain.com’}
| %{
　　　　　 Set-Mailbox $i -EmailAddresses @{remove=$_}
　　　 }

}
Just replace the domain.com with your own.
