Microsoft Transporter Suite crash unexpectedly when migrating from IMAP to Exchange 2007 Sp1

I have serous problems when migrating from IMAP server to Exchange 2007 sp1

I started some tread here http://social.technet.microsoft.com/Forums/en-US/winservergen/thread/a8e546bf-de1e-40f7-bc7f-58d858a10aaf

I found this

Transporter Suite uses EWS in exchange to pump data from IMAP mailbox to Exchange mailbox

I think that IIS crashes and after trying different configurations nothing happened.

That i try to add more memory to Exchange Server and Client from which i import mailbox but still MMC is crashing

After that i start powershell and try to migrate with MOVE-IMAPmailboxToExchange cmdlet and after couple of hours Powershell crash with Out of memory error .

Than ... i call Microsoft support. They say that the problem is unknown to them i they do not know how to resolve it.Good news for me

I decide to forget Transporter Suite and use ImapSync from my Linux server.After hours of research how the program works i found that lunux ImapSync has the same problem and the same error - Out of memory .I start to search google for that error and found that the problem maybe is from that some emails are bigger that usual .Some guy complain that one mailbox has 60 MB message and there ImapSync crash with out of memory .So i check on which mailbox Trasnporter Suite crashes and surprise - that e-mail has 130mb message file in inbox folder. Now i am testing to remove these files and try to migrate again .I hope that testing will succeed and migrate everything

Someone with same issue ?

Hi,

After searching our internal database, I notice a similar case with your issue. It seems a known product issue and our Dev team currently works on the issue.

Solution has been found

After deep investigation i found that MMC and Powershell crash when trying to migrate large e-mails.
Then we search for bigger files in out mail server and found some mail items that are larger than 100MB

After deleting everything that is bigger that 30 MB migrating complete succesfuly.

Now i am happy and ready to erase myself at the pub tonight
