I have tried to uninstall our Exchange Server, because we have moved to Office 365.
But before I could uninstall, my Exchange server said i needed to delete the SystemMailbox Users, so I did that.
After that it said I needed to delete all of my Mailbox Export Request, but I can't delete them, without the System Mailbox User...
I tried to recreate them with the command "setup.com /preparead" without luck. The new accounts gets new names, and then the mailbox requests won't recognise them.
Is there any way I can delete these mailbox requests without having the System Mailbox Users?
