Hello,
I migrate our infrastructure from an AD2008 Forest & Exchange2010 Organization to a new AD2012 forest & Exchange2013 organization.
For user continuity purpose, I would share freebusy and GAL sync over the 2 infrastructure during the migration.
For GAL sync, FIM2010 well works.
For freebusy, I configure freebusy according to : https://technet.microsoft.com/en-us/library/bb125182(v=exchg.15).aspx
this works well when 2 different namespaces are used, the problem come when I want to use the same on each parts.
I couldn't add an availabilityaddressspace for it:
[PS] C:\>Add-AvailabilityAddressSpace -ForestName smtpdomain.com -AccessMethod PerUserFB -UseServiceAccount $true -domainController "dc01.olddomain.local"
Received a referral to olddomain.local when requesting CN=OLDDOMAIN,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=olddomain,DC=com from dc01.newdomain.local. You have specified the wrong server for this operation.
+ CategoryInfo : NotSpecified: (0:Int32) [Add-AvailabilityAddressSpace], ADReferralException
+ FullyQualifiedErrorId : 2D8BFC3,Microsoft.Exchange.Management.SystemConfigurationTasks.AddAvailabilityAddressSpace
smtpdomain.com is declared as internal relay on each oranization.
I don't found any solution on google or Bing (just one post with no more answer

I don't know if it's a bug or a impossible configuration.
Someone ever see this ?
Thanks, BR
