Office 365 - Add Alias - contoso.com

Hi Experts,

Trying to add alias addresses to all mailbox accounts so that they can have @contoso.com as an additional mailbox.

I have come up with this script but it does not seem to work:

$Users = Get-Mailbox

Foreach ($User in $Users){

   $ProxyAddresses = (Get-Mailbox $user.alias).emailaddresses
   Foreach ($address in $ProxyAddresses) {
        If (($Address.PrefixString -eq "smtp") -and ($address.AddressString.split("@")[1] `
        -eq "contoso.com")) {
              $ProxyAddresses += $Address
        }
   }
   Set-Mailbox $user.alias -EmailAddresses $ProxyAddresses 
}

Open in new window

Any ideas?

Sorry the last error was my fault. here is the correct error:

Cannot process argument transformation on parameter 'Identity'. Cannot convert
value "firstname.surname" to type "Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter". Error: "Cannot convert hashtable to an object of the following type:
Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter. Hashtable-to-Object

Here is the script I am trying to run:

 $Users = Get-Mailbox -resultsize unlimited

 Foreach ($User in $Users){
 
 $a = Get-user $user.alias
 $FI = ($a.firstname).substring(0,1)
 $LName = $a.LastName
 $Email = $FI + $LName + "@contoso.com" 
 Set-Mailbox $a -EmailAddresses @{Add= $Email}
