NK2 Exchange Migration

Last Modified: 2017-12-14
We are currently migrating users mailbox from one domain to another completely different one.

We are exporting their mail in pst and importing them to a new domain.

How can we make sure their cached email addresses (NK2) are imported again to the new Exchange?

Both Exchange servers are 2010
Watch Question


To Export Mailbox From One Exchange server to Other use New-MailboxExportRequest


If you have already exported Mailbox/PST file then use Get-MailboxExportRequest to see mails exported or not


If you want to Change any Export request then use Set-MailboxExportRequest


I hope this helps

I already used those commands but what I am looking for is the cached email address (NK2).

Are these imported with those commands?

Exchange 2010 now provides a server side cache for auto-completion of e-mail addresses. In previous versions such as exchange 2003 and exchange 2007 auto-complete data was stored locally in the outlook profile on the local PC in an NK2 file. If the users outlook profile was ever recreated, all their auto complete data was lost.

Because this auto complete data is stored on the server, it is available to the user regardless which PC they are using. Exchange 2010 also makes this auto complete data available to mobile devices running Windows Mobile Device version 6.5 or higher.

Thanks but my question is if I exported their mail in pst from @abc.com and imported their mail to another domain @xyz.com is their outlook cached lost??
It looks Like what you are are asking is possible Via Outlook (if it's connected to Exchange server). You can try solution given below. Since you have PST. I think it will be a easy task.

You can easily export mailboxes database from Outlook (if it's connected to Exchange server) by using Stellar OST to PST Converter. The software exports Outlook OST file data to PST format without any data loss. Download the software from here: https://www.stellarinfo.com/convert-ost-to-pst.php
