I'm Installing Exchange 2013 SP1 on the domain environment on which exchange 2010 was installed before but it isn't available now because it was installed evaluation and for test and it isn't avalable now.

in Exchange 2013 mail box role setup in mailbox service stage it gives me the error copied below:

I found these articles but doesn't apply to my case because I don't have access to exchange 2010 server (It has been deleted from VM):

http://social.technet.microsoft.com/wiki/contents/articles/5317.recreate-and-enable-missing-arbitration-user-accounts-and-mailboxes-in-exchange-server-2010.aspx

https://support.microsoft.com/en-us/kb/978776

how can I completely remove exchange 2010 from Active Directory?

What should I do to fix this error and install exchange 2013?

Hello

tip: need manually delete with adsiedit.
https://goo.gl/tTwLBQ

Thank You Sneff_Gabor,

But I've done this before starting exchange 2013 setup (before doing "setup /preaparead" command).

But still that error occurs now. the error seems to be about creating Arbitration emails or something like that.

any other ideas?

I found these Info inside ExchageSetup Log file:

 [1] [ERROR] Database is mandatory on UserMailbox.
 [1] [ERROR-REFERENCE] Id=SystemAttendantDependent___04cc4ecfc25f40a6bf13fe2fb767ae60 Component=EXCHANGE14:\Current\Release\PIM Storage\Discovery
 [1] Setup is stopping now because of one or more critical errors.

Hello

have got  in "Microsoft Exchange System Objects" ou systemMailbox... delete and try again install

Thanks Sneff_Gabor for your reply,

I went to ADSIEdit again!

Connected to Default Naming Context

Navigateed to the following objects and Deleteed them.

DC=Domain,DC=Com -> OU=Microsoft Exchange Security Groups

DC=Domain,DC=Com -> CN=Microsoft Exchange System Objects

Turns out They were created by Exchange 2013 setup and now I'm in deeper hole..

Tried to run: setup /mode:Uninstall but got error again

now even when I try to run installation again it says I had an unsuccessful uninstall and should complete that first.

since I've deleted Exchange User Groups in OU, Can't use Exchange PowerShell tool and can't connect to exchange server...

how can I start over fresh?

I'm trying to run exchange setup from another windows server.. I don't know what to do else...

Can any one guide me to do a fresh clean installation of exchange 2013 sp1?

Thanks in advance...
