Old exchange 2003 server gone; a few mailboxes still point to old store

I need to delete three mailboxes that remain in AD listed from an old exchange 2003 server long gone. After doing a Find/Advanced in AD I came up with the three in question. Can I just use Exchange Tasks and Delete Mailbox?

Also, one of the mailboxes is:
SystemMailbox{9AFFE912-F96D-bla bla bla} Type User

Can I just zap this one as well? This is all prerequisite to removing the extinct exchange server from ESM.

The answer to your question is you do nothing to those mailboxes, just move all your users and public folder across and decommission the old server as normal.

For further reading, see the following link: http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/06ad9dc4-ec81-4b5c-a9ee-6e00c08c7198

You can delete the mailbox DBs on your old server no problem as part of the migration to 2007/2010.

The legacy Exchange 2003 server to which I refer is physically non-existent. I am presently in a pure Exchange 2003 environment with a single Exchange 2003 server remaining and operational. The link you provided references moving them to 2010, which is not what's in play here. I am trying to clean up legacy objects prior to deleting the non-existent server from 2003 ESM (you can reference my other open question on the matter if you need more background information). This is strictly asking how to get rid of the mailboxes that still show as residing in the message store of the non-existent server.

Essentially what I'm chasing is this:

- I want to delete all object attributes related to the old, non-existent server.
- I want to then delete the non-existent server from ESM.

My mistake, okay before you proceed, take a full system back up of your server. I'm also assuming you have another set of 3 system mailboxes for your current 2003 box too?

If those attributes relate to a server which is no longer part of your network and will not be, then you can delete those objects.

Once done you can proceed and remove the server from ESM. Drill down to the servers view -> right click the server in question -> All Tasks -> Remove Server.

I would as a precautionary measure, restart your current Exchange 2003 server to ensure it boots and mounts all stores okay, rather than during your next maintenance cycle to realise that there is a problem.

cool - that's what I was hoping for. I did a system state backup but I'll backup the store now and then proceed. I'll update accordingly. Sounds right, reads right. Stay tuned.
That sounds as if the old Exchange 2003 server was not cleanly decommissioned.

You can certainly try to remove the mailboxes and server using ESM, if this fails I might be  tempted to pay Microsoft and open up a PSS case with the subject something like "unable to remove objects and exchange server using ESM on exchange server that has already been decommissioned".

If it was not cleanly decommissioned, then there will be _many_ other artefacts left in AD that should be cleaned up.

Here is an article to assist if removing the server does not go cleanly via ESM, to remove via AD: http://support.microsoft.com/kb/833396

So I got an email this morning telling me to update this thread. I apologize but I've been on vacation over the Memorial day holiday and will attend to this shortly. I do intend to reward experts for this but have not had a chance to get to it yet. Patience everyone.

That did the trick. Removed the Exchange attributes then nuked the mailboxes from the extinct Exchange server. From there it was a piece of cake to Remove Server under ESM. Good call netflo.
