Outlook 2003 to 2010 migration problem using Microsoft USMT

When using the microsoft User State Migration Tool (USMT) to migrate users from a Windows XP/Office 2003 environment to a Windows 7/Office 2010 environement

I encountered the following error messages when launching Outlook 2010

“Cannot start Microsoft Outlook, cannot open the outlook window. The set of folders cannot be opended. The attempt to log on to Microsoft exchange has failed”

“Cannot open your default e-mail folders. The Attempt to log on to Microsoft Exchange has failed”

The resolution to this was to ensure i was using USMT v4. (this cannot be downloaded on its own, its part of the windows 7 IAK download)

And install a patch to office 2010 http://support.microsoft.com/kb/2023591

After this the migration was succesful. Users Mailboxes, Signatures, Arhives and nickname settings all migrated as expected.
