Uninstalling Exchange 2010 Server

Hi

I am not able to uninstall Exchange 2010 - I get the message "some settings are not  valid, please specify an existing server roles to uninstall" (see the attached screen shot)

I untick the mailbox role and continue then I get the following error message -

"Mailbox Role Failed

Error:
The following error was generated when "$error.Clear();
      get-MailboxDatabase -server $RoleFqdnOrName | remove-MailboxDatabase

" was run: "Exchange server "Mail-Server.domain.local" was not found. Please make sure you typed the name correctly.".

Exchange server "Mail-Server.domain.local" was not found. Please make sure you typed the name correctly.

I tried installing to and get a similar error.  It looks like I am in a loop. I just want to remove this.

Any ideas?

The issue has been resolved by MS Engineers - it was a nightmare, it took 6 Engineers about 30 hours to uninstall 2010 and install 2013

Not necessarily the cleanest way, but have you tried to force a removal?

Confirm full AD connectivity, reboot the box and confirm again.

Hi

I am trying to do it manually using this -

http://www.itbigbang.com/how-to-manually-uninstall-last-exchange-2010-server-from-organization/


When I installed the Exchange initially there was no Domain Controller on the server. I was relying on membership to 2003 domain.

You can't install Exchange without a DC available.  Is there a DC there now or not?

HI

there is a DC available - I tried the manual uninstall

once the ADSIEDIT - CN = Microsoft Exchange  and CN = Microsoft Exchange Server  removed.

and rebooted the server I am unable to install a fresh copy.

And of course it knocked out my Exchange 2003 server _ I thought it was only removing the organisation from the server.
I cant uninstall 2003 either.  It would be good if anyone knew how to do this manually.


I am in trouble, logged a call with microsoft.

In the past I could not install Exchange 2013 because there was 2003 server there. Now I am in a dilemma which do I get up first.

First you need to sort out the Domain not found error.   Are you using the right DNS server, can you ping the DC etc.

MS PSS will help you urgently of course.
