Some emails in .PST files are in Chinese after being extracted from Exchang

[joseffosse]

I am supporting a customer who has a Server 2003 SBS server.
We recently migrated this customer to a new Exchange 2013 server running on a Server 2012 server.
Some of the mailboxes weren't exported to .PST files before this migration was done and the old Server 2003/Exchange 2003 SBS was demoted.
We still have a copy of the Exchange 2003 .EDB file from the old server and have been using a utility called Kernel for Exchange Server (see the screenshot) which is able to extract individual email accounts and place the contents into Outlook .PST files.
The problem is that there is a very small percentage of emails in two user's email Inboxes and Sent items folder that are in Chinese (instead of English).
This business doesn't have any Chinese employees and have never sent any emails in Chinese.
What can be done to fix this issue?
Please let me know if any further information is needed.

It sounds like a bug with the software. If you do not have the original SBS 2003 machine, I think you are out of luck. You can also try restoring from backup after staging a new 2003 server in a separate domain, but I am not sure if that would work either.

It has been hit / miss with 3rd party software that reads the EDB file offline. I think you should try Microsoft Exmerge utility to convert all exchange data into outlook file format. Download from here: http://www.microsoft.com/en-us/download/details.aspx?id=2743

I think it will help you.
