Exchange 2007 move-mailbox script for bulk move using powershell

Posted on 2008-10-05
Last Modified: 2012-08-27
We are about to move users cross forest from Exchange 2003 to Exchange 2007. We have tested the command below which works perfect for moving a single mailbox. As I am not an expert with powershell, can somebody assist with creating a script that will do a bulk move of mailboxes based on a txt file with users aliases (or sam account).

This is what we have completed for 1 mailbox:
$SourceCredential = Get-Credential  (This is the username and password for source domain)
$TargetCredential = Get-Credential (This is the username and password for target domain)

Move-Mailbox -TargetDatabase "EX07\First Storage Group\Small Mailboxes" -Identity eric_sdaly -GlobalCatalog dc01.targetdomain.local -SourceForestGlobalCatalog SourceDomainController -NTAccountOU "OU=Secure,OU=Ireland,OU=User Accounts/Groups,DC=targetdomain,DC=local" -SourceForestCredential $SourceCredential -TargetForestCredential $TargetCredential -SourceMailboxCleanupOptions MailEnableSourceAccount

Hope someone can help on this.

That should be quite easy actually :)

PowerShell has a nice CSV File Reader that can be used to read the input file, we could just loop through using that.

Imagine your text file (call it users.csv for this example) looked like this:


The column header is important, with that we can do:

$UsersCSV = Import-CSV -Path "users.csv"

Which will let us loop through each like this:

$UsersCSV = Import-CSV -Path "users.csv"
foreach ($Line in $UsersCSV) {
    Move-Mailbox -TargetDatabase "EX07\First Storage Group\Small Mailboxes" `
        -Identity $Line.Username -GlobalCatalog dc01.targetdomain.local `
        -SourceForestGlobalCatalog -SourceDomainController `
        -NTAccountOU "OU=Secure,OU=Ireland,OU=User Accounts/Groups,DC=targetdomain,DC=local" `
        -SourceForestCredential $SourceCredential -TargetForestCredential $TargetCredential `
        -SourceMailboxCleanupOptions MailEnableSourceAccount

We can access each line with the ForEach loop, then we get the Username column with "$Line.Username". The ` used above just allows us to split the command over several lines, tends to make it easier on the eyes.

This is what you need. $users = get-content inputfile.txt  will read the aliases or samaccountname from the inputfile.txt . For each loop will iterate through the list and move the mailboxes.


$SourceCredential = Get-Credential  (This is the username and password for source domain)
$TargetCredential = Get-Credential (This is the username and password for target domain)
$users = get-content inputfile.txt
foreach ( $user in $users ) {
Move-Mailbox -TargetDatabase "EX07\First Storage Group\Small Mailboxes" -Identity $user -GlobalCatalog dc01.targetdomain.local -SourceForestGlobalCatalog SourceDomainController -NTAccountOU "OU=Secure,OU=Ireland,OU=User Accounts/Groups,DC=targetdomain,DC=local" -SourceForestCredential $SourceCredential -TargetForestCredential $TargetCredential -SourceMailboxCleanupOptions MailEnableSourceAccount
if ($? -ne True ) { 
write-host "Move-Mailbox Failed for user $user ."
