Wrong received dates

[gerard.kieffer]

Hello,

I've moved all my emails (about 1000) from an IAMP account to another
and I downloaded them to Outlook again.
Now all the dates are set to the date on which I moved my mails to the
new IMAP server instead of the date I received the email.

I know that these are two different fields in the email header.
Is there a possiblity to get the right dates back into outlook ?

Mozilla Thunderbird uses the right field and still displays the correct
date (I think it looks for the dates the email was sent)

Thanks for any help.
