Migrating ProxyAddress attribut

by Beefstew at 2013-02-15 02:28:07

Hi all,

I need a script that will export the ProxyAddress contents of all groups in one domain and and import to a new Domain

Basically I’ve migrated all distribution groups from Exchange 2003 to Exchange 2010, mail enabled and added x500

I just now need to add the old proxyaddresses to the migrated groups and do not want use Recipient Policies

Any idea’s please?

On the old domain I would just store the information like so. (filter however you want!)
Get-ADUser -Filter * -Properties proxyaddresses, mail | Export-Clixml -Path \Path\to\File.xml
Using XML will keep the data structure but you will lose methods and invocation.

In you target domain, use the Get/Set Mailbox cmdlets to add proxyaddresses
$Old = Import-Clixml -Path \Path\to\file.xml
$MB = Get-Mailbox $Old.Name
$MB.EmailAddresses +=$Old.ProxyAddresses
$MB | Set-Mailbox

I have not tested this. Let me know how it goes.
