Exchange 2007 Search Database for Keyword

[john...@gmail.com]

Exchange Server 2007 SP 1 running on Windows Server 2003.

We need to search our email databases for any emails regarding a
certain email address. Before, I've used the following syntax:

PS> get-mailbox –Database DB1 | Export-Mailbox –SubjectKeywords
"Discovery Keywords" –TargetMailbox Administrator –TargetFolder
'MyData'

Now, when I run this in the Exchange Management Shell as administrator
on the server, I receive the following error:

"Error occurred in the step: Moving messages. Failed to copy messages
to the destination mailbox store with error: MAPI or an unspecified
service provider. ID no: 00000000-0000-00000000"

Searching this group and the 'Net led me to believe that SP 1 changed
permissions on the mailboxes; therefore, I've tried running the
command

"Get-MailboxDatabase -identity "BANG\First Storage Group\Mailbox
Database" | Add-ADPermission -user "Vert\ExMerge" -ExtendedRights
Receive-As, Send-As"

[Certain stuff changed, of course]

This hasn't helped.

I could ask why the export-mailbox no longer works with SP1, but I
don't really care. I've come to expect Microsoft to break something
when they fix something else. I care only about this: How do I make it
work?

And one other thing, in case anyone at Microsoft reads this post: How
hard would it be to add a "Search Database" option to the Action menu
in Exchange Management Console? It's insane to require us to flip
between a CMD and a GUI for email management.
