Well, I just pulled a world-class screwup.  A little background:  I did an 
in-place migration of Exchange, bringing up a new Ex2K3SP2 server and running 
ADC to make connection agreements to my other domains (unfortunately, I still 
have about 28 domains - believe me, domain consolidation is my next project).  
I then moved user mailboxes to the new server.  That's been working quite well, 
EXCEPT:

When I ran the ADC, I'd only just upgraded three of my domains to Active 
Directory (Win2K3 from NT4).  The ADC didn't convert those accounts properly.  
The users in those three domains were stuck in a bizarro state; their logon 
accounts worked just fine, but showed no Exchange properties (no matter how 
many times I ran domainprep).  The ADC created disabled ADC_<gobbledegook> 
accounts for all of them in an OU that I specified in my root domain (where my 
Exchange servers reside).  Those accounts had the users' Exchange properties.  
If you looked in Ex5.5 Admin, though, the mailboxes still pointed to the 
correct domain/account.  ADUC showed something entirely different.  The users 
never knew there was a problem.

I've been trying to fix this since New Year's.  Well, to make a long story 
short, don't frigging ask me why, but today I took it into my head that it'd be 
a good idea to delete the OU containing those disabled user accounts.  
Immediately, all the users' mailboxes went bye-bye.

Well, I've spent most of the day trying Active Directory recovery scenarios to 
recover that deleted OU and/or the deleted disabled user accounts.  I did 
finally manage to restore the accounts via ldp.exe.  Yuck.  (It's about 75 
users all told.)  Trouble is, all their mailboxes are empty.

Now, before I build a recovery server and exmerge their mailboxes from my 
backups, is there any better way anyone can think of for me to actually recover 
their mailbox data?  And what's going to happen if I start the directory 
service on the recovery server?  The last thing I want is to have to restore 
those frigging deleted accounts again.

Obviously, the users have lost all their distribution group memberships, too.  
That, right now, is the least of my worries.

Let the lesson be, no matter how good your backups may be, they aren't as good 
as you think they are.  And don't delete OUs!

I shall now go drink heavily.
