Error in moving mailbox to Exchange 2007 database

Hi Expert

I can't find any solution. Please help.

I have just installed Exchange 2007 Standard SP1 with Updates Rollout 4 installed. The Exchange Server 2007 is running on Windows Server 2008 Standard Edition with fully patches.

I've started to move 120 mailboxes from Exchange 2000 to Exchange 2007. Only 5 out of 120 were not successfully moved from Legacy Mailbox status to User Mailbox status.

I then started manually move one by one. It is still persist. I checked the Event Log. It showed Event ID 1008 with following error message:
The move-mailbox task for mailbox 'J Jen' failed.
Error: Failed to copy messages to the destination mailbox store with error:
MAPI or an unspecified service provider.
ID no: 00000000-0000-00000000

I tried Exmerge on Exchange 2000, it has no problem to extract that 5 legacy mailbox to PST files.

Does anyone has encountered it and any advice for me to resolve this issue.

If you can get it to a PSt then export it to a PST, delete the users mailbox account and create them a new one in 2007 then import  the PST.
As a quick fix, why don't you just take the PST file that you got from the old Exchange 2000 server, manually create the 5 new mailboxes, and then merge the PSTs into the newly created mailboxes?

This KB article mentions circumstances similar to yours, although the content of their 1008 Event is different.
Thats exactly what I just said......
The last thing that you can check is to see if you need to set "Allow Inheritable Permissions" under the security for the for the 2003 Storage Group/Mailbox Store.

(This will have to be done in the ESM for 2003)

Else the only option that you are left with isto Exmerge those 5 mailboxes to a PST file

I managed to figure it out the solution. Resolved by using ADSIEDIT utility. Hints: look for LegacyExchangeDN attribute.
