Creating Linked Mailbox Accounts in Exchange Resource Forest

I have an Exchange 2007 SP1 system deployed in an Active Directory Resource 
Forest.

I'm looking at the ExchangeUtils.CreateMailbox  functions in ILM 2007 FP1 
and I do not see a version that allows me to specify the 
msExchExternalAccount that is required when creating a Mailbox Enabled user 
in a resource forest.

I know from a powershell perspective, the syntax is different when creating 
a mailbox for a normal user and when creating a mailbox for a linked user in 
a resource forest.

Can I do this using the CreateMailbox functions or do I need to write my own 
MA that will perform the correct powershell for this scenario?

Does anyone have experience using the standard CreateMailbox function and 
then adding the msExchangeExternalAccount attribute afterwards in an Export 
Attribute Flow rule?

Thanks in advance!

I know with the GALSync solution in ILM 2007 FP1 a powershell CMDLET is used 
to finalise the created contacts.  The URL below sheds some light on the 
issue:

Hope this helps.
