MapiExceptionNoSupport: IExchangeFastTransferEx.TransferBuffer failed hr=0x80040102, ec=-2147221246

These last couple of days I've been migrating a customer from Exchange 2003 to Exchange 2010 SP1.
All users were moved successfully, except one. On this user we got some strange error messages in the move-requeststatistics command and on the HUB transport responsible for the move.
The complete error message is posted at the bottom.

On this user the move-request failed after just some MB, and the troubleshooting begun.
These are the steps I took:

• Use Exmerge on 2003 for .pst migration - Failed. The error message in the exmerge logfile is as follow:
  Error copying messages from folder '\Inbox' (MAPI_W_PARTIAL_COMPLETION) [22:14:27] Trying to copy messages in folder '\Inbox', individually. To avoid duplicates in the target store, messages will be merged and not copied into the target store. [22:14:27] Error getting Contents Table. (CopyMessagesToDestFolder)
• Migration to another Exchange 2003 mailbox store - OK
• Migration to Exchange 2010, gives the error message below.
• Export to .pst from Outlook - OK

The solution for me was to use PFDAVAdmin and to reset the DACL on the mailbox. Tried the Check DACL state, before the Fix, and it said it was ok. But apparently not.

When the DACL was reset, the move-request went successfull.
