Hello,
I recently installed a new domain and have the current functional level set to 2012. I have been troubleshooting getting exchange 2010 to work on a server 2012 machine for awhile now, and want to lower the domain functional level so that I can add a 2008R2 server and run exchange from there.
I found these commands to lower the functional levels and the errors generated are below them:
- Set-ADDomainMode -Identity domain.local -DomainMode Windows2008R2Domain
Set-ADDomainMode : The functional level of the domain (or forest) cannot be lowered to the requested value
At line:1 char:1
+ Set-ADDomainMode -Identity domain -DomainMode Windows2008R2Domain
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (domain:ADDomain) [Set-ADDomainMode], ADException

Set-ADForestMode : A referral was returned from the server

+ CategoryInfo : ResourceUnavailable: (HCBC:ADForest) [Set-ADForestMode], ADReferralException
+ FullyQualifiedErrorId : ActiveDirectoryServer:8235,Microsoft.ActiveDirectory.Management.Commands.SetADForestMode
Can anyone help me with downgrading the domain? Or possibly how I can get around this by recreating things? Thank you in advance.
