Exporting mail between Exchange servers
Posted on 2013-11-02
We have just migrated from an exchange 2007 server to exchange 2010. unfortunately there was no way to create a trust between the 2 sites and emails have been exported to PST and then reimported to the new server.
All the mail has come across but now if a user attempts to reply to an email that's been imported the user gets the mail tip that state the address is no longer valid. I suspect this is because outlook is looking for the X400 address from the previous exchange server.
Is there anyway I can tie these emails back to there new email addresses on the new system ?
