Hello,

I have been tasked with creating about 160 Exchange contacts. I'm finding that some of the email address listed are secondary email addresses for other users. I am in need of assistance for the following.

- Determine which contacts in my list have already been created.

- Determine which addresses on my list are already in Exchange as secondary SMTP addresses for different contacts/mailboxes.

- For the addresses that are not in Exchange I will need to mass create them.

- For the existing contacts that have addresses in my list, I will need to delete the secondary SMTP that matches ones in my list and create a new contact for the SMTP.

Really not sure how to work this one. Any assistance would be appreciated.

Thanks in advance,

Hi,

Prewritten scripts can be found in the repository:

I'd suggest asking your question over in the Exchange forums for your version of Exchange, but be aware that it is highly unlikely someone will have a script already written that will meet your requirements.

Get-Recipient will show you which email addresses exist.

Hi Green-Tech,

Please refer to this script to start, which can delete secondary SMTP addresses based on the string pattern "*@domain.local":

Get-MailContact -OrganizationalUnit "domain.local/OU" -Filter {EmailAddresses -like "*@domain.local"} -ResultSize unlimited -IgnoreDefaultScope | foreach {
$contact = $_
$email = $contact.emailaddresses
$email | foreach {
if ($_.smtpaddress -like "*@domain.local") {
$address = $_.smtpaddress
write-host "Removing address $address from Contact $contact.name
Set-Mailcontact -Identity $contact.identity -EmailAddresses @{Remove=$address}
$contact | set-mailcontact -emailaddresspolicyenabled $false} }}

Refer to:

Powershell script to delete secondary SMTP addresses of Exchange 2010 Mail Contacts

I also recommend you can post your current script and specific issue for a better response.

If there is anything else regarding this issue, please feel free to post back.

Best Regards,
