  I am trying to get the script to work but it runs and ends and nothing was changed.

  This is what I have in the script:

  $ConfirmPreference="None"  
    
  $i = 0  
  get-mailbox -resultsize unlimited | ForEach-Object {  
      $maile = $_  
      for ($i=0; $i -lt $_.emailaddresses.count; $i++)  
          {  
              if ($_.emailaddresses[$i] -like "smtp:*@domain1.com")  
                     {  
                  $badaddress = $_.emailaddresses[$i]  
                  $maile.emailaddresses -= $badaddress  
                  $maile | Set-Mailbox -EmailAddresses $maile.emailaddresses 
                  }  
          }  
  }

  The above gives an error about consecutive pipeline commands but if you remove the *@ in the -like statement then it runs but with nothing happening.

  What release of Exchange?

   

  If it's 2010, try this:

  Hi

  What about below script:-

  Get all mailboxes into an Array
  $mbxs = @(get-mailbox -Resultsize Unlimited)
  
  #Iterate through each mailbox
  foreach ($mbx in $mbxs)
  { 
  	#Create two copies of the email addresses in the returned mailbox
  	$CurrentList = $mbx.emailaddresses
  	#the second copy is the one where the changes will take place.
  	$NewList = $mbx.emailaddresses
  	
  	#Iterate through each address in the address list.
  	foreach ($Address in $CurrentList) 
  	{ 
  		#see if the current address matches the domain you are wanting to remove
  		if ($Address.tostring() -match "OLDDOMAIN.com") 
  		{ 
  			#If the match is found, remove that address from the list.
  			$NewList -= $Address
  		} 
  	}
  
  	#Overwrite the old list with the new list.
  	set-mailbox $mbx -emailaddresses $NewList

  Hi

  The above Script is good, but I suggest to add on more condition in the Comparing Part becasue Pegoto said he would like to move two domain

  if ($Address.tostring() -match "OLDDOMAIN01.com" -Or "OLDDOMAIN02.com")

  Also I think he missed a closing bracket "}" in the end.

  Cheers

  Change 
    get-mailbox -resultsize unlimited |ForEach-Object { 
  to 
    $mailboxlist = get-mailbox -resultsize unlimited
    $mailboxlist | ForEach-Object {
  For some reason in Exchange 2010 sometiimes it works better (script was prepared for Exchange 2007)
