Mistake: removed in stead of disable Exchange 2010 mailboxes.

I am in the middle of uninstalling an Exchange 2010 sp3 server without the need to migrate or keep mailboxes.

I started the uninstall and it said that i could'n t uninstall. So i first disabled the mailboxes and as a stupid mistake i removed all mailboxes in stead.

They are still residing in the disconnected Mailbox. When i click on one of these mailboxes, i can only connect them to user. So that's why i think it really happend.

When it was disabled i could reconnect it.

But now: users are still active in Active Directory (They should!!) and the mailboxes are in the disconnected mailbox folder, waiting to be purged.

Before i use Hyena or another thirth party tool, what can i do here?

1) i need to remove the old Exchange 2010 server, but didn't finish because of errors
2) My mailboxes are removed, so the active directory users will also be removed, but when?
3) i have 1 backup of my Domain controller (not the Exchange server)
4) What can i do to keep my current active directory users and remove the Exchange 2010 server from my domain?







Stupid mistake: removed in stead of disabled exchange 2010 users. When will AD delete the user accounts?

AD does NOT remove the user accounts if you just deleted the mailboxes. So as long as you do not need access to the old mailboxes, nothing to do more here.

Hi Qlema, i just connected the mailboxes to the right user in AD, after that, i did a disable of the all the Exchange users, just to be sure.

you will need to select the disable mailbox and not the delete mailbox. if you disable then the mailbox will be in soft delete state and will allow you to reconnect it if needed, and it wont delete the user object. if you select to delete the mailbox it will still go into the soft delete state but it will also delete the AD user object. you can disable the mailbox so that the user AD object isnt affected and you can still uninstall exchange provided that all other prerequisites are in place. you need to be sure arbitration mailboxes are also removed or you will not be able to uninstall exchange.

If you remove instead of delete mailboxes, you remove the AD and the mailbox. AD accounts can be restored from the AD Recycle Bin using the AD Administrative Center console, and then you can reconnect the mailbox again.
As TimGreen says, you need to either migrate or remove all mailboxes before the mailbox stores can be removed, and then Exchange uninstalled.

Hi Peter. Exchange is now already uninstalled, and my AD accounts are still there (the mailboxes were in disconnected mailboxes in Exchange). The purpose was to uninstall Exchange; that part succeeded.

Because my AD accounts are still there (and Exchange is already uninstalled) i think this is ok now?

Or will there still be a schedule (even if Exchange is uninstalled) that my AD acounts will be deleted? Or because of uninstall of Exchange i do not need to worry anymore?

No, those accounts will not be deleted, so you have completed your removal of Exchange.
