I am trying to get the exchange transporter suite to work to migrate 700+ users from an imap mail server to exchange 2007 sp3. I have read through several articles and support posting but am still getting an error on majority of email messages. I have tested with messages that are roughly 50kb in size as well as much larger messages. It does not seem to matter on the size.
Warning:
Could not create message item (12/26/12) for user (user@domain.com).
Warning:
The request failed with HTTP status 413: Request Entity Too Large
I have followed KB article 953526 and restarted both the service and did an iisreset. Any other thoughts or suggestions would be great as we would really like to make use of this tool.
