I setup a temp Exchange 2016 server, imported all the mail and attached the users. After rebuilding the old server and installing Server 2016 and Exchange 2016 I migrated the mailboxes to the new server. I now need to uninstall exchange from the temp server but I can't get to the EAC or the Exchange Powershell. When I try to uninstall Exchange from Control Panel I get
Uninstall can't continue. Errors:
This mailbox database contains one or more mailboxes, mailbox plans, archive mailboxes, public folder...
What's the best way to uninstall Exchange under these conditions
