How can I restore emails to a PST from a 10Gb mailbox


A user removed a lot of his emails from his mailbox, but his mailbox still shows as 10Gb probably due to the database not being purged due to no backup being taken? I can't recover his deleted items using Outlook as they are not there.

Is there a way to export his raw mailbox to a PST or series of PST's so that those emails are readable again? I have tried ExMerge on the mailbox but i think due to the size it refuses to work (or is size not a factor with Exmerge?)

I need to get a copy of this whole mailbox on my desktop so I can recover details.

Exmerge still only supports ANSI format and not unicode. Unicode supported in Outlook 2003 and above for PST files allows them to be larger than the 2GB limit.

You need to export the mailbox to a UNICODE enabled PST from Outlook 2003 or greater or use exmerge to export individual folders to individual files and therefore keep the pst file below 2GB.

Error message when you use the ExMerge tool to export an Outlook 2003 mailbox to a .pst file: "The item could not be moved"

How are you trying to recover deleted items.You need to logon as the user to recover the deleted items.
I don't think even if get a PST file with exmerge you would able to recover the deleted items.
For future use make the following registry changes on the workstaions if using outlook 2k-2k3 to retrieve even the hard deleted items.

1> Configure user's mailbox in Outlook 2007.
2> Create new PST as highlighted in attached snapshot.
3> Simply move emails from Mailbox to PST.
4> I have PST of 13 GB and works fine.

Please have a read of the following article which explains how to Export to .PST files using EXMERGE in Exchange 2003 (and how to split up data larger than 2Gb into separate .PST files):

I can use Exmerge no problem, I'm familiar with splitting into 2Gb PST and Unicode etc. But...
The deleted items do not show up when I connect an Outlook client (2007 or 2003) to the mailbox, these deleted items are physically in the .MDB but do not show in the recover deleted items area. If you know of a tool to extract from the MDB that may be my best bet. I don't want to use Exmerge really now.

There are some tools that range from a few hundred dollars all the way up to about $900 and some of these are:
