Hi, I maintain a lot of email contacts for partner companies. One of those has just changed their email domain. So their email address go from user@company.com to user@newcompany.com. I'm using Exchange 2007. Does anyone have a script that would allow me to change just these contacts email domain whilst leaving the 'user' part intact. I have looked at using admodify, but that appears to leave the externalemailaddress field set to the original domain. Thanks for any help

You definitely need a PowerShell script to do so. What you could try to do is the following $contacts = Get-MailContact | Where {$_.PrimarySmtpAddress -like *@olddomain} foreach($contact in $contacts){ $newmail = $contact.primarysmtpaddress.tostring() $newmail = $newmail -replace "olddomain","newdomain" Get-MailContact $contact | Set-MailContact -primarysmtpaddress $newmail -externalemailaddress $newmail }
