Move Mailboxes to Target Mailbox Database

From crazy907 - 2/26/08 11:13 AM

Is it possible to move more than one mailbox at a time with this script?  I would like to set the maxthreads to 8 but can't get it to move more then 1 at a time.

 Thanks

Like desireechance, I'm looking to make this work across forests.  I've made some headway with the following but still no luck mass moving mailboxes.

 1.  Preppended the source domain to the usernames in aliasies.csv.  So 'john' becomes 'sourcedomain\john'.

2.  Edited $mailbox = get-mailbox -Identity $i.FN to read $mailbox = get-mailbox -Identity $i.FN -domaincontroller sourceDC.

I can successfully move a single mailbox using:

Move-Mailbox -TargetDatabase "Targetserver\First Storage Group\Mailbox Database" -Identity username -GlobalCatalog GCserver -SourceForestGlobalCatalog SourceGCServer -NTAccountOU "DC=xxx,DC=xxx,DC=xxx" -SourceForestCredential $SourceCredential -TargetForestCredential $TargetCredential

I set $SourceCredential and $TargetCredential when I first open Exchange Management Shell, before running the above command.

 Update 3:33PM:

OK, I figured out a way to do this across forests.

get-mailbox -DomainController Exchange2003DC -Credential $SourceCredential | move-mailbox -TargetDatabase "Exch2007\First Storage Group\Mailbox Database" -SourceForestGlobalCatalog SourceDC -GlobalCatalog nike -DomainController Exch2007DC -NTAccountOU "DC=xxxx,DC=xx,DC=xxx" -IgnorePolicyMatch -SourceForestCredential $SourceCredtial -TargetForestCredential $TargetCredential

Obviously you have to set $SourceCredential and $TargetCredential first.  I've only tried this using the -ValidateOnly switch so far but it appears to work.

have not moved across forests however did tweak it to pull using Full Names...sample script to export user by fullname from AD below... 

On Error Resume Next

Const ADS_SCOPE_SUBTREE = 2

Set objConnection = CreateObject("ADODB.Connection")
Set objCommand =   CreateObject("ADODB.Command")
objConnection.Provider = "ADsDSOObject"
objConnection.Open "Active Directory Provider"
Set objCommand.ActiveConnection = objConnection

objCommand.Properties("Page Size") = 1000
objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE

objCommand.CommandText = _
    "SELECT Name FROM 'LDAP://OU=whicheverpathyouwishtosearchin,DC=yourcompany,DC=com' WHERE objectCategory='user'" 
Set objRecordSet = objCommand.Execute
objRecordSet.MoveFirst

Do Until objRecordSet.EOF
    Wscript.Echo objRecordSet.Fields("Name").Value
    objRecordSet.MoveNext
Loop

------------------------ 

 now to xfer mailboxes over from powershell...

$mailbox = $null
$database = $null
$existingMailboxes = @()
$nonexistingAliases = @()

if ($args.Length -lt 3)
{
 write-host "Usage: MoveMailboxes.msh aliases.csv [-TargetDatabase [<>]]"
 return
}

## Check if the given target database exists
$targetdatabase = $args[2] -replace '"',""
write-host "Target database:" $targetdatabase
$database = get-mailboxdatabase $targetdatabase
if ($database -eq $null)
{
 write-host "The target database doesn't exist:" $targetdatabase
 return
}

$data= import-csv -path $args[0]

## Check if there is a mailbox associated with the given alias
foreach( $i in $data )
{
# $mailbox = get-mailbox | where {$_.alias -eq $i.alias}
 $mailbox = get-mailbox -Identity $i.FN
 if ($mailbox -eq $null) {
  $nonexistingAliases += $i.alias
 } else {
  $existingMailboxes += $mailbox
 }
}

write-host "No mailbox associated with below aliases: "
$nonexistingAliases

write-host "Move below mailboxes to the target database:" $targetdatabase
$existingMailboxes
$existingMailboxes | Move-Mailbox -TargetDatabase $targetdatabase

I have been playing with this script to see if I can get this to work when moving mailboxes from an Exchange 2003 organization, across forests to an Exchange 2007 organization.  any ideas?

Theelectronicchild - if you've updated the script to get it working with E2k7 RTM in your environment, please feel free to update the changes into this wiki page. That's exactly what this site is all about and we all appreciate your contributions!

I have noticed that .msh is the old file format - If you end up with the exchange shell telling you MoveMailbox.msh is not recognized as a cmdlet, function...(yadda yadda) change the extension to .ps1 - after some tweaking to the script above it works wonders in mass mailbox moves, thanks for posting
