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):

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?
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.
