What you do is create a new email address policy and apply it to an OU.  That is what EAP is for.

Should it retain any existing email addresses or aliases?  Or just reset the email?  

Is the address generated off of a standard, or do you want to recycle the characters to the left of the @ symbol in their existing email address?

Sorry for not being more specific:

The addresses were not created via Address Policy. They were created manually. Therefore, no standard.

I simply want to keep the characters on the left side of @, but change domain name;  i.e @contoso.com to @comp.com

I've already move the users to a specific OU

Do you want to keep existing addresses, or replace them?

HIGHLY recommend you test this on a single user in a sub OU since I'm writing it off the top of my head.  let me know if you get any syntax errors or whatnot and I'll do my best to address them.

make sure you change the OU path as well.

$newdomain = "newDomain.com"
$oldDomain = "oldDomain.com"

foreach ($mb in (Get-Mailbox -OrganizationalUnit domain.com/path/to/OU -resultsize unlimited | ?{$_.primarysmtpaddress -ilike $oldDomain) {
     $userID = $mb.primarySmtpAddress.split("@")[0]
     set-mailbox $mb.alias -EmailAddresses "SMTP:$($userId)@$($newdomain)"
}

Correction: I like to keep the current smtp address and just add a new one: For example

current: Joe_smith@contoso.com
new: joe_smith@comp.com

Since there is no standard, firstname and lastname attributes cannot be used.

To confirm, at the end of the script should Joe Smith have only joe_smith@comp.com, or should he have a Primary address of Joe_Smith@comp.com and an alias address of joe_smith@contoso.com

If you want to keep both addresses, DON'T run my example above.

If you only want the single address with the new domain, then this will work.  (above has typo)

$newdomain = "newDomain.com"
$oldDomain = "oldDomain.com"

foreach ($mb in (Get-Mailbox -OrganizationalUnit domain.com/path/to/OU -resultsize unlimited | ?{$_.primarysmtpaddress -ilike $oldDomain)) {
     $userID = $mb.primarySmtpAddress.split("@")[0]
     set-mailbox $mb.alias -EmailAddresses "SMTP:$($userId)@$($newdomain)"
}

This will work for what you needed.

Import-Module -Name ActiveDirectory
$OU = "OU=Name,DC=xxx,DC=XXX"

$usernames = Get-Aduser -Filter * -SearchBase $OU -Properties GivenName,SN

foreach ($username in $usernames)
{

# New email address will be "existingemail@yournewdomain.com"
$NewEmailaddress = (Get-CasMailbox -Identity $username.displayname).PrimarySmtpAddress.Local + "@yourdomain.com"

Set-Mailbox -identity $username.displayname -EmailAddresses $NewEmailAddress -EmailAddressPolicyEnabled $False

}

Open in new window

placed a # sign in front of set-mailbox and $Newemailiaddress will display the email address that will assign, so you can test it without changing anything at this point.

Import-Module -Name ActiveDirectory
$OU = "OU=Name,DC=xxx,DC=XXX"

$usernames = Get-Aduser -Filter * -SearchBase $OU -Properties GivenName,SN

foreach ($username in $usernames)
{

# New email address will be "existingemail@yournewdomain.com"
$NewEmailaddress = (Get-CasMailbox -Identity $username.displayname).PrimarySmtpAddress.Local + "@yourdomain.com"

$NewEmailaddress
#Set-Mailbox -identity $username.displayname -EmailAddresses $NewEmailAddress -EmailAddressPolicyEnabled $False

}

Enphyniti,

Here is the error I get:


You must provide a value expression on the right-hand side of the '-' operator.
At C:\Users\modContacts.ps1:4 char:115
+ foreach ($mb in (Get-Mailbox -OrganizationalUnit '***********/Contacts/********** | ?{$_.primarysmtpaddress - <<
<< islike '$oldDomain') {

Review the original code again: You made several non-operational changes.

Yes, I do see the operation changes. I also see how Enphyniti's script would have worked, but I decided to use the Set-mailcontact command as the following:

$Users = Import-CSV 'C:\contacts.csv'
ForEach($User in $Users)
{
write-host "Processing $($User.alias)"
set-mailcontact -identity $user.alias -ExternalEmailAddress $user.email
}

This took care of my needs. Thanks!
