    Question Reasons why Exchange Migration Wizard skips mail

    Hi

    Still struggling to migrate two of our mailboxes.

    Other than attachments being too large, what other reasons are there for the Exchange Migration Wizard being unable to retrieve messages?

    On two of my mailboxes no messages are imported only warnings issued (without a reason as to why no messages could be retrieved).

    Thanks
    Paul

    there's a registry key on the machine the wizard runs on for the numer of failures before the wizard gives up. i set it to 0, which means that he will not stop at all. look it up in the manual, I forgot the exact registry key...

    Thanks. I will give this a try but I don't get any errors, only warnings. It seems to report a warning for each folder it is attemting to get data from. The associated message in the log is "Requested x, got 0".

    OK. Made the registry change and tried again.

    No success I'm afraid. I need to know more about the reasons why the wizard might have difficulty retrieving items (entry generated in the wizard output window is "Could not retrieve all items" so I can start to track the cause.

    Any one know more about the wizard than is in the migration guide?

    If you only have two "problem" mailboxes, why not just export them using Outlook into a new *.pst file, run the scanpst repair tool, then use the Zimbra pst importer.

    Sorry for the delay in responding, I didn't receive a notification of your post.

    I would prefer to perform the migration in a consistant manner across the user base. The work I am doing now is a feasibility test and will have to do the real migration later on. I haven't looked into the differences between using the migration wizard and the export/import pst method (if any).

    Also, I may be involved in the migration of one of our clients (with a much larger user base) and would prefer to resolve the issues first.

    Just an update. I never got to the bottom of this but went ahead and implemented the test system. The system is the hands of the users now and they are checking for an important items missing as a result of the migration/import process. So far no one has reported any problems.

    I will not be spending any more time on this issue.
