I installed Microsoft Exchange server on a blank 2008r2 server a few days ago. After installing Exchange I had to remove and re-enable the Active Directory Domain Services role to fix another issue. When uninstalling Exchange earlier today the uninstaller crashed and I had to restart it. After starting the uninstaller I now get the error message:
Error:
The following error was generated when "$error.Clear();
Set-MailboxServer -Identity $RoleFqdnOrName -CalendarRepairWorkCycle $null -CalendarRepairWorkCycleCheckpoint $null
" was run: "The operation couldn't be performed because object 'PLSERVER.mydomain.co.uk' couldn't be found on 'PLSERVER.mydomain.co.uk'.".
I really just want to uninstall Exchange server in any way possible. I am not quite sure how to tackle this error message though, especially since I am very new to Windows server (I come from a *nix background).

I've been through a manual uninstall of Exchange. It sucked. It required a call to Microsoft Support and many hours on the phone with them.
The gist of it was that you get the install media and find all of the MSIs, right click on each and select
uninstall, lather rinse repeat. Then, manually delete all Exchange references from the registry.That said, this is entirely unsupported outside of the direction of Microsoft. I really recommend opening a ticket with them.
