We just migrated from Server 2003/Exchange 2003 to Server 2008 R2/Exchange 2010
We had to start with a Fresh Server 2008 R2/Exchange 2010 install due to errors in our old config.
So we pulled down the .pst files for each user and imported them into the new user accounts within Exchange 2010.
THE QUESTION: Are there transaction logs from the old Exchange Server 2003 that I can import into the Exchange 2010?
THE PROBLEM: Internal emails that were sent to other internal users before the Server change out are unable to be "replied" to. An error comes back essentially telling me that the mailbox is not there. I'm assuming that the header in the email is trying to go back to the old Exchange 2003 Server?
Thank you in advance for your time!
