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?
