I've just moved a VIP mailbox from 2003 to 2010 and although the move report was sucessful (no baditems) the mailbox is now only 12MB in size when it was 350MB before. Is there any way to reverse this move and get the items back? Is there a 2003 version of a soft deleted mailbox? I know this only came in with 2010 SP1 but it would be handy if there was a method or tool to get this out the a legacy database.
Thank you in advance
Run the command :Get-MoveRequestStatistics -id username | lf to get the difference between the total mailbox size reported and the bytes that are actually transferred during the move..

Thanks for the quick response. Unfortunately the move request was cleared before I knew there was a problem with the mailbox. The move history does show the expected itemcount and mailbox size though.
I would not suggest trying to restore the deleted object as that may damage the 2010 mailbox. If there is a viable backup I would suggest a restore to the recovery storage group, export to a PST and then an import with omit duplicates. I've done many migrations 2003->2010 and have never seen items plainly missing though.

Yes, we have moved more than 3000 mailboxes here already and this is the first one where something like this has happened. By unhappy coincidence the backup for this storage group failed over the weekend so I would have to go back to Thursday for a restore. I've logged a call with MSPS to see if anything can be done before having to resort to that.
Thanks for the advice.
Not sure anything would be left in the 2003 EDB/STM at this point but get an offline copy of the database and open it with Lucid8's DigiScope http://www.lucid8.com/product/digiscope.asp 30 Day DEMO license which will allow you to open the offline database so that you can Browse and Search all the Mailboxes and items and see whats available for recovery. If the desired data is there you can then obtain a license so that you can Export mailboxes, folders and individual items to PST & MSG or Recover directly from the Offline database into a Production server, even cross version 2003--> 2010
@Jonas: There were 105 corupted items initially which were actualy archive mail stubs. These were fixed but running a "relink" in the archive application (ArchiveOne) and then the move request was resumed. I suspect that there is a bug when you resume a move request from 2003 to 2010 but this isn't something that we have seen on all the previous occasions where the same process has been followed (+/- 300 mailboxes)
@Troy: Thanks for the suggestion but we would need downtime to get a copy of the database which even though this is a VIP will not be possbile at this stage.
As far as I know, it only restore the backup.
Exchange 2010 SP1 soft deletes the mailbox on the source database after move mailboxes. But Exchange 2003 has not this statement, I test in my lab, and don’t find the moved mailbox in mailbox recovery center. So maybe the moved mailbox should be cleaned in source.

What about reconnect the deleted mailbox from the Exchange 2003 source server? You can try reconnecting the disconnected mailbox to another account (i.e temp account), then export the mailbox contents?
of course once exported, delete the recovered mailbox from the source server.
Thanks for the responses to this question.
I logged a support case with MSPS who could find no cause or solution, but suspected that it may be down to database corruption on the source. As the mailbox does has been deleted by the move we could not verify this.
