You can do a Cross Forest Migration as outlined here http://blogs.technet.com/b/meamcs/archive/2011/06/10/exchange-2010-cross-forest-migration-step-by-step-guide-part-i.aspxOr if you just want to migrate the mailbox data use a 3rd party product like Lucid8's DigiScope http://www.lucid8.com/product/digiscope.asp to open an offline copy of the 2003 database so that you can Browse, Search, Export Mailboxes, Folders and Individual Items to PST & MSG or in your case you can Recover/Import/Migrate direct from the Offline 2003 EDB into the production Exchange 2010 Server.Troy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 with Lucid8's DigiScope

You can use Lepide Exchange Recovery Manager tool to restore mailboxes from offline database to Live Exchange Server. It can search, export and restore mailboxes from corrupt information stores to Live Exchange and PST as well .

With Exmerge I export mailbox to pst and connect to Outlook - good(Folder name, message - all availible) When I import "New-MailboxImportRequest -filepath \\myserver\pst$\mymailbox.pst -mailbox mymailbox" my Folders named "". My Folders in russian lang. How I can fix this?

Hmm could be the default Locale setting. Check out these articles http://demazter.wordpress.com/2010/03/23/export-mailboxes-using-exmerge-and-exchange-2003/ http://www.windowsitpro.com/article/email/using-exmerge-with-multiple-languagesTroy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 with Lucid8's DigiScope

I try to export with English and Russian locale. If English locale I have "?????? ?????????????" folder name (import with powershell and connect pst to Outlook). /resetfoldernames - very big job for 6000 users mailbox. If russian locale - I have "" folder name only import from powershell, if connect pst to outlook - good name. May be type locale to New-MailboxImportRequest?

ok so just to be clear you export to PST with ExMergeDo you then open the PST with Outlook and that's when you see folders with ??? or "" What version of Outlook are you opening the PST with?Troy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 with Lucid8's DigiScope

I export to PST in locale Russian, my outlook 2010 - if connect PST to Outlook - folder name good, if import with powershell "New-MailboxImportRequest" - folder name ""

Seems to be Outlook problem. Please run Outlook.exe /resetfoldernames Hope it is helpful. Fiona Liao TechNet Community Support
